IntechOpen eBooks, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 20, 2025

Continuous and excessive use of synthetic fertilizers in food production generates strong pressure on agroecosystems. Therefore, it is necessary to study standardize alternatives that promote environmental health, such as biochar. Biochar (a blackish solid obtained from the pyrolysis vegetable waste, industry animal or water processing waste) characterized by its high content mineral carbon, presence functional groups, richness nutrients potassium (K+). Its soils improves organic matter cation exchange capacity (CEC), which promotes crop nutrition. In addition describing biochar manufacturing processes, this chapter aims emphasize role a fertilizer, stimulating effects soil microbiome enzymatic activity, positive plant health. Understanding biofertilizer can be considered an ecological strategy for production. However, agricultural sector must consider limitations fertilizer.

Rice-based cropping systems are the predominant sources of livelihood for farmers in South Asia, where soil quality decline is a major concern. An experiment was conducted at Bhubaneswar, Odisha, India, 2018–2019 and 2019–2020. It comprised two rice cultivars, ‘Manaswini’ (M) ‘Hasanta’ (H), three nitrogen management practices—100% test-based (STN) (N100), 75% STN + situ green manuring (Sesbania) (N75+GM), 50% (N50+GM)—in main plot. Meanwhile, sub-plots consisted tillage methods succeeding toria–sweet corn, namely zero (ZT), conventional (CT), furrow-irrigated raised bed (FIRB).

Spring wheat was grown on a loess-derived Luvisol under the conditions of two farming systems (conventional and organic) five forecrops (sugar beet, spring barley, red clover, winter wheat, oat) over period 2021–2023. In conventional system, mineral NPK fertilization pesticides (herbicides, fungicide, insecticide, retardant) were applied at recommended rates for wheat. Mechanical weed control also used (double harrowing). organic fertilizer Humac Agro fields harrowed twice. No plant protection products conditions. The system proven to have an effect reducing yield, average by 23%, compared (the grain yield was, respectively, 4.59 t ha−1 5.96 ha−1). spite lower potential, cultivation significantly improved quality health-promoting parameters this cereal grain. Except total nitrogen potassium content, contributed significant increase in content dietary fiber (by 0.89 p.p.), o-dihydroxyphenols about 19%), polyphenols 12%), increased following elements: Se, Mg, Ca, Cu, Mn, Fe, Zn. Among forecrops, clover sugar beet had most beneficial (including amino acid composition EAAI index), followed oat (especially conditions). other (spring barley wheat) clearly deteriorated To sum up obtained research results, appropriate management (forecrop or fertilizer) contributes high nutritional relative reduces gap farming.
