What amendments increase retention in sandy soil?

Sandy soils release water quickly and can dry plants out between waterings. I was able to convert the sandy spots in my Utah garden into sponge-like structures using specific soil amendments. These amendments can retain moisture near plant roots while also allowing for drainage, preventing the waterlogged conditions associated with clay soils. By adding the right materials, your sandy soil can be very productive.

Use amendments properly for optimal results. I mix coconut coir with compost at a ratio of 1:3 before planting. Incorporate the materials to a depth of 8 inches where root systems grow. Don't apply amendments on the surface only. Water well after incorporating to engage the moisture retention capabilities. Your plants will respond in a matter of weeks.

Biochar provides irreversible gain with stable carbon structures. Unlike compost, which decomposes over time, biochar can last for decades. I add 2 gallons per 10 sq ft every year to my vegetable beds. With time, it has transformed sandy soil into a moisture-holding loam with no need for intensive, repeated applications.

Keep track of progress with the squeeze test. Take some amended soil and squeeze it in your palm. It should form a loose ball, holding its shape for a moment before falling apart. Pure sand falls apart immediately. I check in monthly during the growing season. Your observations inform your follow-up amendments to achieve uniform moisture for healthy plants.
