Improve Clay Soil with Sand?

[@Chels_Rene]

My Dad added half dump truck load of manure, half of sand, got some bottom land topsoil, tilled it in our shale clay soil. We had a very impressive garden. Added this and that each year.

[@jonas3333]

Best explanation of why I should hesitate to add sand yet and I've watched a lot. Very informative! At 54, I find myself wishing I had gone for higher learning all about soil when I was younger. It's just fascinating!

[@southbridgeforestHOA]

I added about 8 yards of compost to my 30x30 front yard garden. if you have clay soil adding lots of compost helps, but the soil is still pretty mushy. Adding 10-20% sand together with the compost really helps the soil's friability/breaks up easily. the problem most people have is they like to break down what they hear into simple facts, when actually in nature it's typically more complex.

Thank you for this video! Very well explained. I am a professional gardener and have been looking how to explain to people more precisely why I don't like adding sand to clay. I use manure, compost, wood chip and have transformed my clay soils with this organic matter!

@@mommadramapreps8668I agree. Organic matter seems to disappear over time

[@danielvonbose557]

I have the opposite problem of too much sand. I have decided to increase the clay from about zero to five percent or so. I obtained a red clay of about 30% clay that I am using to mix with my sand in a 1:5 ratio, that is one part clay to five parts of soil. Think of 2"" of clay on top of soil you are prepared to work 12" deep. Do this and you have mixed the clay with 10" of soil below. The soil diagram works much better going from sand to some clay than it does the other way around. The properties of a nearly pure sand get neutralized pretty quickly with the increase in clay. From there it's just biology. I have found it's the pure sand that burns up the organic matter. I have a theory that the soil microbiome depends on the clay as well as organic residues to form soil crumb structure.

[@nicholasbenedetto6319]

Sand by itself won't really work. You do need other things that will help loosen the structure. I added sand, gypsum, peat moss, and sawdust. It worked fairly well. The following year I added composted leaves and that made it almost perfect.

[@frederickwolf8413]

[@bruce-le-smith]

we live on a clay flat by the ocean and the clay itself turns into cement in the summer, so agree that adding just sand does seems like one step closer to actual cement! I've added a lot of wood chip mulch over the years and it's amazing how the clay just absorbs it. but the yard does get a little less sticky every year. we're probably down from 80% clay to only 65% hah

Jason - great!!!! I've been using Charles Dowding techniques - developed for the market garden - on all of my plantings starting last year. At risk of veering from the topic at hand... I'm having fun with an experimental wildflower garden using the No Dig technique. The planting is just coming into it's own after planting out too late on June 1. So much less labor, sweat, time, plastic - and it seems to have worked. I covered a blackcap & raspberry bed, after scything, with cardboard, then added a mix of soil, manure, composted wood chips. I should have started it in the fall because of the watering regimen it needed this summer. Otherwise, it seems to be a success. This fall I'll try planting using the same technique- allowing the seeds to stratify over winter. Warmest regards! Jennie

[@cranstjs]

Thanks much for your video. I've been struggling in North TX, near Fort Worth, for at least 6 years, living in this residential area for 15 years now. Since I was here from the day the house was built forward, I've seen the whole life span of my Bermuda grass sodded yard. The soil is at least 30 to 40% clay, very clumpy. The builders here choose to level some and then dump yards of Sandy Loam on top to the tune of about 2 inches worth. Then they lay the sod on top. Mostly what I read about that technique is, it's a bad idea. Because the sod likes the soft loam and roots in a shallow way in the loam an mostly ignores the tougher clay to some degree. Also, the first few years the underlying weeds from Mars came through the sod and I finally had to hire a pro lawn service TruGreen to whip and chain the weeds for a few years and they finally got under control. So for about 8 years my lawn looked very healthy with TruGreen coming out every year to do the weeding and fertilizing and such. Turn the page and around 2012, we had 3 years of drought. (And yes, I have an irrigation system). I started noticing dead circles in my front yard at one end. And over the years, in spite of bringing in pros to analyze the problem, with mixed opinions and fungus treatments, my front lawn truly looks more sick with more areas that are troublesome. I even dug up 6 inches of soil/sod in the dead areas, put in new soil and new sod, and a year later, it died again. As if the soil has gone bad and just has some poor health now. At least 30% of the front yard looks sick. The backyard looks twice as healthy and grows thicker and green. Although it too has about a 1 yard area in one part that is struggling where again, I replaced the soil/sod and it still struggles. This year I tried taking about 600 lbs of sandy loam and just trowled it over the unhealthy areas in an effort to do the "comeover" technique of side growth. It's still early so time will tell if that helps. I was tempted to top coat the whole front yard with about an inch or so of sandy loam (and I see many videos about doing things like this to level out a yard). I'm running out of ideas and it's pretty frustrating. And usually by the time July/August hits, it gets so hot and dry here that the sick spots simply can't stand up to the strain. Any thoughts?

[@FraserValleyRoseFarm]

Thanks Jeffrey - it can be a tough thing to overcome the initial soil prep. I'm not so much a lawn guy, but I do wonder if a topdressing with organic matter along with overseeding a grass blend might be an approach. I've remediated a compacted area in our yard this way, but much different climate!

[@raj66kas]

I'm in Flower Mound and yesterday I tried using an 3 inch auger in my backyard. The auger managed to dig about 6 to 8 inches and then hit solid ground. The soil is so compact that the auger just spins and doesn't penetrate the compact soil. I had to add water to soften the soil. In the past, I broke 2 forks due to the hard clay soil.

[@VinceEspositoJr]

Thanks for referring me to this video. Much to think about - also know as "brain mulch." I think I have a lot to do with my clay soil before I can get close to a "steady state" of no or low till situation. But we do need somewhere to put leaves, grass clipping and such, and based on your other soil video, I will now add wood chips. I do find it beneficial to try to get in a cover crop at the end of the season (e.g., winter rye and maybe clover) and till or disc that is at some point. Also, I find that crop rotation can help some. Unfortunately, I live in the middle of hay fields so I have been using plastic otherwise I can't keep up with the weeds. I am starting to shift to something more permeable so that I can expose the soil to the air.

[@FraserValleyRoseFarm]

Hi Vincent - thanks for your input. My situation is pretty manageable (on a relatively small scale) but if I were trying to make change on a larger property or more difficult clay, I'd probably focus on the crop cover mixes as well.

Thanks John. Sounds like a good book that stand the test of time.

Thanks for the input George!

[@worldcitizenra]

The discussion of whether or not adding sand as an amendment for clay is a catastrophic change or cost (beginning at the 6:50 mark) understates the issue if a person has to go to the high side (250 cubic feet of sand) in order to amend their clay soil. At 60 cubic feet (the low end of the presenter's estimate) it is not significant. But at the upper end of the estimate, it is significant. Consider that the 20X20X2 foot volume discussed as being amended works at to 800 cubic feet. Adding 250 cubic feet of sand represents adding just short of 1/3rd the volume of dirt to get just a 10% amendment in soil that started out at 40% clay. For many places, the clay soils could easily be more than 40% clay. For example, the country where I live has soil ranging from almost 40% clay in the southern & central parts closer to the sea, but up to 70% clay in the northeast where I live. I won't be considering sand as an amendment for the soil here.

You should do a garden tour. I would like to know what the white flower behind you is? Off subject. I saw another KZbin video of someone who advised to plant your rose bushes deep to promote roots from the stems? Is this good advice?

[@FraserValleyRoseFarm]

Thanks Lori - and the white flower is cleome. It's been in bloom forever! I'm going to withhold any definitive judgement on deep planting for a bit. I've always favored the crown at soil level when transplanting almost anything - perennials, shrubs, trees. It seems the most natural placement to me, and because the crown (or bud union) is an important and vulnerable spot on the rose, I like to have it where I can check on it. I know that Paul Zimmerman (a real rose guy who I respect a lot) has written in favor of deep planting - but not because of adventitious rooting. He advises it because the buried stems will provide more stability against wind rock. My take on wind rock is that it's often associated with roses planted in a planting hole that's too large, to generously amended with organic matter, and with too loose a soil. Once firmly established in the native soil, my roses no longer "rock" in the wind. The additional rooting is an interesting angle - I wonder if the advice is intended for own-root or grafted - presumably the grafted roses were bought on the idea that the rootstock provides additional benefit, so the rooting of the scion variety would be undesirable? Finally, I do hear from those in cold climates that deep planting is helpful for winter protection. I'm not convinced. If you're dealing with a truly hardy variety to your climate, depth should offer no benefit, and a tender variety - good luck either way!

What if you have an area of heavily compacted clay (from machinery) with no top soil left? What can sustainably be done to enable appropriate plants to grow in it? Thanks! ( it's land around a reservoir in Essex- a dry region in UK)

[@FraserValleyRoseFarm]

The fast answer to get growing in one season is to use a raised bed or bottomless container. Compacted soil can be a slow, tough thing to correct. Some cover crops are good at addressing compaction: Oilseed radish, red clover, oats, rapeseed (or a wide mix of various cover crops). I don't know how free you would be to do a more disruptive adjustment (tilling organic matter or sand deeply) - but even modest additions of organic matter over a longer timeframe can help.

[@matthewfarrell317]

I think a big thing is people get stuck thinking that only one thing is best without having a good look. I am in Melbourne, Aus (Mornington Peninsula area) and we have clay loam soil, even tho I am closer to the cost (less than 10km's) we still have a lot of clay, but not solid. The thing is I would never think about trying to change it. The simple reason is a more loamy soil would actually make it worse. We have had if you are lucky 80-100mls of rain in our area over the 2 1/2 months of summer. Its been a pretty dry and moderate summer. When I do a deep irrigation on the orchard we built in the front yard last year, I can go 2-3 weeks before needing it again, just because the soil can hold onto that water. The plants love it and saves us water. A more loam or sandy loam would lose too much water. That said I am building the soil with organics, even tho it was filled with worms etc when I took out the grass, it was a lawn for 30 years with no nutrients put in, so thick sugar cane mulch for organics, top dressing with compost etc.

Is it better to stab the soil with a pitchfork to aerate and just sprinkle sand over top. Is Pete moss necessary?

[@FraserValleyRoseFarm]

It's hard to know what will work with such overall slow drainage. Sure you could try and see if aerating or breaking up some of the surface layer will help, but I tend to think any new "drains" will silt up again pretty quickly. Another thought is to look into cover crops that break up compaction, like oilseed radish, rye or sudangrass - of course, you'd have to do a little research into what grows well and is available in your climate and what season to try it for.

[@watermelonlalala]

Every time you plant in a container you are starting with a brand new soil structure so what is wrong with that? Doesn't seem to hurt.

[@FraserValleyRoseFarm]

Hi Brendan. There are advantages and disadvantages to tilling in sand or other amendments. You have to pick what works for you. My preference is to maintain and improve soil structure if I can, but if I were faced with a very stubborn thick soil, I wouldn't take any option off the table. One difference to container growing is that I would generally fill entirely with a potting mix chosen for superior water/air balance and drainage qualities. When working with a natural soil you won't have the same opportunity to "engineer" these qualities (unless you intend to replace the entire bed with something new, and even then, it's not quite the same in-ground). The improvement in texture by amendment may be partially or fully offset by losing soil structure. YMMV

Even a not draining clay soil can get much better with the right treatment. Sorry for bad english.

[@faqthefarmer]

same goes for sandy soil. organic matter an the aggregation will improve the ability to hold water and things like nitrogen and potassium.

Great video! You're not one of these "anti-sand" guys. I trust that soil triangle with my life. I trust the soil scientists that recommend about 15% organic matter. Sure you might need to add a lot of sand if you are doing commercial farming. But if you dig a hole for your plant in your backyard garden, and you backfill that hole with 40% sand, that hole will have great drainage which might be just enough to let the core roots breathe and prevent the worst excesses of flooding. That of course depends on the size and scale of the hole. In any event, understanding the three particle sizes and their respective pros and cons, it really liberates a gardener and allows them to think outside of organic solutions. I think inorganic solutions (meaning particle sizes) are just as important if not more important. Hydroponics takes inorganic farming to its furthest logical endpoint. Hydroponics is successful and conserves water and fertilizer resources. That's not to say organic matter is entirely useless, but organic matter is easy to come by and obvious to most gardeners. But I think most gardeners don't understand the three particle sizes and the soil triangle. One last thing I want to express is that, if you don't have sand at your disposal because it's too expensive and not local to the area, I would be interested to see a study where clay is taken from the local soil, superheated in a fireplace or kiln, turned into hardened clay, pulverized into large sand-like particles, and reintroduced to the garden to improve drainage. Because once clay is superheated, it cannot return to its former state. In other words, you cannot sculpt clay pottery with clay that has already been heated. So I hypothesize that clay could actually improve soil drainage if super heated and turned into sand-sizes spheres. This is an experiment I want to try because sand is fairly expensive to buy compared to simply heating local clay. Although the latter is more labor intensive.

[@FraserValleyRoseFarm]

Thanks Trevor for your insights. My quite silty soil behaves rather like clay. One spot in the garden must have been an old sandbox - and I have to say that the blended soil around that area is quite a pleasure to work with. I might not go to the trouble and expense of adding sand in bulk, but I'm happy to use what's there!

[@FraserValleyRoseFarm]

Sharp

[@johnskillen6208]

just seen video . we have a foot of soil then clay . have started digging 10 feet deep and mixing in cow manure. will also build up ground level 4 or 5 feet. this will be a 50 by 80 foot plot goal it a orchard. any thoughts . we have material and a hoe. we have started but now snow. will carry on in spring will give a year for it to settle before tree planting

[@petertr2000]

Wonder if you're still reading/replying? I have a heavy clay lawn. I'm hoping that simply top dressing with compost 1-2 times per year will eventually improve the soil. Worms dragging it down, aerating the soil, then bacteria and funghi feeding on it etc.

[@FraserValleyRoseFarm]

Hi Peter. I think if I were aiming to improve a lawn over clay soil, I might also use a plug aerator and add some sand with the organic matter. I guess it depends on how much effort you want to put into it, but the slow addition of both organic matter and sand (distributed by soil critters) will definitely improve a heavy clay over time.

I had a small tree stump removed from my garden recently. I removed all the wood chips left from the stump grinding and then filled in the hole with miracle grow garden soil and regular bagged soil.

[@JESUSsaves2345]

If you add organic materials to the clay with some sand to plant a tree would that work

[@FraserValleyRoseFarm]

In general organic matter helps, but don't go overboard in the planting hole - they tend to compact down over time, and that undermines the support of the roots.

You sure can rake in manure and a light application of sand each year to gradually improve organic matter, so long as you have reasonable drainage to begin with.

[@kerrymidkiff2072]

Hi Jason how are you. Hope all is well. I know I had asked you before about miniature Rose's. I'm really having trouble. They seem to die on me in a couple of days.

[@PercyBowls]

So I have clay soil in my yard, and I dug a plot of land down like 18 or 20 inches or so and Im filling it with compost and perlite, not sand. Is this going to be aerated enough, and will I be ok on drainage? will it be a good starting growing medium? will I run into the problems mentioned here about disrupting the soils natural systems? Brand new to gardening!

[@FraserValleyRoseFarm]

Hi Nick. I think you're right to be concerned about the drainage - that's the first thing you need to solve. Compost and perlite can be nice additions to the soil, but it will take some for the soil to settle and develop structure again.

[@ST3LIANA]

In the situation of having to amend the garden soil of a new construction, where you have to dig out a serious compromised layer, how would you recommend the new layers to be? A base of gravel for drainage and sand maybe? And then the top soil? How thick would you say the gravel layer has to be? Thanks!

[@bengrogan9710]

Depends on how warm and how much water you have - the gravel alone does nothing without somewhere for it to go Eg: if you had a french drain nearby then any layer would need to be an inch or so only if graded properly

[@taylormoore3400]

Simple analogy sand plus clay equals concrete

[@luckwagon]

Here's a crazy question... I'm trying to plant some roses in super heavy clay soil. Just now saw your video, after attempting to amend about a foot down, with peat moss and soil conditioner. I don't have sand, but I do have a bag of crushed quartz that's about the same consistency as sand. I won't use much, but would this be a worse idea than using sand? Also, what are your thoughts on gypsum?

[@FraserValleyRoseFarm]

Hi Kathleen. The quartz would be about the same as sand for its properties. Gypsum only helps in sodic soils, so you'd want to know the chemistry of the soil a bit before you hit it with gypsum.

[@annebromwich8224]

Very good. Thankyou.

[@godsliberator4973]

Sand is Acidic and if you mix to much the composition wont ve right depending on other factors. What I need is thermal heating.

[@vikramsinhzala6405]

What should we do to improve clay plus salty land?

[@FraserValleyRoseFarm]

With high salt levels this might be a time to look up gypsum as a solution

[@alliecatnz]

If you start with a clay pan (for example once the top soil is scraped off and a house built) then instead of mixing sand or organic matter in then simply replacing the topsoil with more friable loamy, mixes of garden soil can work. So add 20-30cm on top of the clay (topsoil) and leaving the clay as it probably once was (the subsoil). Plants should thrive. Organic matter will also help. The clay will hold moisture and nutrients and release it to the plants as needed but you can control what mix of topsoil you’d like, then you can always mulch that too with arborist mulches. Like a layered cake.

[@edzakete.3700]

I was thinking I’d add the sand to my compost pile?

[@stevehatcher7700]

In other words, if you added a bunch of sand to your clay soil, expect to wait years, if not decades, for the soil biology to re-bake the cake and make that new soil texture become the new soil structure. However, if you added a little bit of sand, plus organic matter/compost, every year, you could get closer to a decent sand incorporation into the clay, and improving that structure, faster than adding it all at once.

at 76 my aim is to quickly improve drainage and get rid of standing water after even the lightest shower.

Can it not be mixed with soil, because I have noticed many comments that wood chips and soil will compete with plants for nitrogen when mixed, so can I grow annual vegetables in soil mixed with wood chips?

[@FraserValleyRoseFarm]

Thanks - I did a video on the topic of wood chips and nitrogen: kzbin.info/www/bejne/gJusl3x7hd95d9E The effect of wood chips is highest where the soil is in direct contact. If you put them on the surface, only very shallow-rooted plants would see a reduction in nitrogen. If you mix it, the chips will break down faster, and pull nitrogen from a larger area. Either way, it's relatively easy to add supplemental nitrogen to compensate. Liquid fish fertilizer is a decent choice, as would be alfalfa pellets.
