From my experience in coastal SW Florida, building the bleach white sugar sand with compost has made all the difference.

Your numbers will be improved greatly and faster then you might expect as you begin adding organic matter. The downside is that you have to continue to add it because the micro beasts will consume it fast.

When I first tilled my garden plot in 1988 I needed really dark sunglasses to protect my eyes from the bright glare of that white sugar sand. Now I have nice dark soil. My only ongoing plight is dealing with the nematodes that just love South Florida Summer heat!

You may want to also test for the level of organic matter in yur soil. Adding organic matter will help both with the level of Phosphorus and Potash and also with your soils pH as well as aiding in moisture retention. These simple soil tests may be of some help,

1. Structure. From that soil sample put enough of the rest to make a 4 inch level in a clear 1 quart jar, with a tight fitting lid. Fill that jar with water and replace the lid, tightly. Shake the jar vigorously and then let it stand for 24 hours. Your soil will settle out according to soil particle size and weight. A good loam will have about 1-3/4 inch (about 45%) of sand on the bottom. about 1 inch (about 25%) of silt next, about 1 inch (25%) of clay above that, and about 1/4 inch (about 5%) of organic matter on the top.

2) Drainage. Dig a hole 1 foot square and 1 foot deep and fill that with water. After that water drains away refill the hole with more water and time how long it takes that to drain away. Anything less than 2 hours and your soil drains too quickly and needs more organic matter to slow that drainage down. Anything over 6 hours and the soil drains too slowly and needs lots of organic matter to speed it up.

3) Tilth. Take a handful of your slightly damp soil and squeeze it tightly. When the pressure is released the soil should hold together in that clump, but when poked with a finger that clump should fall apart.

4) Smell. What does your soil smell like? A pleasant, rich earthy odor? Putrid, offensive, repugnant odor? The more organic matter in your soil the more active the soil bacteria will be and the nicer your soil will smell.

5) Life. How many earthworms per shovel full were there? 5 or more indicates a pretty healthy soil. Fewer than 5, according to the Natural Resources Conservation Service, indicates a soil that is not healthy.

Because in your area of the world the soil bacteria never stop working at digesting organic matter you need almost twice as much as I would and in your area it can sometimes be difficult to find, but persistants does help.

Ditto what the others said about adding organic matter. You also have very low phosphorus, which promotes root growth and blooming/fruiting. Potassium is a major nutrient as well. You may have virtually no nitrogen if it's been leached out of the sandy soil, and that gives you lush green growth. If you have things planted this year that you want to save, you may have to resort to a balanced fertilizer, and over time build up your soil so you don't need it as much or at all. If it's hot and dry you can use a soluble plant food to water with, or you can sprinkle 12-12-12 or 13-13-13 (or anything relatively close). I know this is a compost forum, but if your plants are at death's door they need CPR before worrying about a long-term diet.

PS We could trade truckloads of soil - my clay for your sand, and we'd both be happier!

Thank you kxcrusadr (and other friends). I think I need CPR so this weekend I'll be at HomeDepot. I think my yard is left with sand only so I need to dump every organic material that I can find in my yard (though I dont know how my wife will re-act). Thanks again
