Placement and Rate of Cricket Frass Regulate Fertility Restoration and Chinese Kale Biomass in Tropical Acidic Sandy Soil
A greenhouse test compared surface placement versus incorporation of cricket frass at 3.125, 6.25 and 12.5 t/ha in acidic sandy soil. At the highest rate, incorporation produced 7.16 g shoot dry mass per plant versus 4.78 g for surface placement and 1.70 g for control, with improved nutrients, microbial activity and lower exchangeable acidity.
