Influence of recycled organic waste amendments on carbon pools, greenhouse gas emissions, and nematode indicators of soil health

This study examined the effects of applying three different organic amendments from sources previously considered waste in a new almond orchard and in a laboratory incubation experiment. The amendments included: 1) compost composed of municipal food waste and yard trimmings as feedstocks, 2) biochar produced from woody debris and 3) liquid food hydrolysate derived from grocery store organics. These amendments were compared to either fertilized (N+) or unfertilized (N-) controls.
