We went through a multi-year drought and, as I analyzed my farm, its growth patterns and fertility levels, I realized we needed to take some steps to offset the next drought. With our sandy loam topsoils and pure sand subsoils, we were drying out too fast.
I felt we needed to do something to capture more of those big dumps that seemed to be the source of most of the rain we did get — things like trampling more organic material to provide a soil mat that would retain more moisture, and feeding the soil life that builds humus and organic matter, became top priorities. I am intrigued by the concept of soil biology releasing tied-up nutrients in the soil. Over the years I have applied some trace minerals, rock phosphate and high-calcium lime, and have done some foliar feeding. However, a truly sustainable/organic farming system should be pretty much self-sufficient, and it appears that mobbing may make that goal more possible.
