Nutrient Dynamics in Sandy Soil and Leaf Lettuce Following the Application of Urea and Urea-Hydrogen Peroxide Impregnated Co-Pyrolyzed Animal Manure and Bone Meal

There is a paucity of data regarding the effect nutrient-enriched biochar amendments on nutrient dynamics in both soil and crops. This important because unlike pristine biochar, applied to minute quantities as large amounts may led over application nutrients loaded it. The current study examined effects phosphorus- nitrogen-enriched biochars macro micronutrients sandy leaf lettuce grown thereon. phosphorus enrichment followed co-pyrolysis animal manure (cow dung) with 25% 50% bone meal (w/w), while nitrogen was achieved by soaking co-pyrolyzed into urea urea-hydrogen peroxide. performances were compared conventional amendment triple superphosphate (TSP) production period two seasons pot experiment. resulted higher microbial biomass carbon ratios than amendment. caused more phosphorus, potassium, magnesium accumulations amendments. nitrogen, calcium, micronutrient elements availabilities all thus, acted reservoir that could provide growing beyond single season.
