Fertilizers and Pesticides: Agricultural Chemistry and Soil Tests
Agricultural chemistry links crop production with soil testing so fertilizers and crop-protection inputs can match field conditions.
Open article →Fertilizers and Pesticides: Chemical Fertilizers and NPK
Chemical fertilizers supply essential plant nutrients; NPK identifies nitrogen, phosphorus and potassium used singly or in mixtures.
Open article →Fertilizers and Pesticides: Manure, Compost and Vermicompost
Organic manures recycle plant and animal wastes; composting and earthworms convert this material into nutrient-rich soil conditioners.
Open article →Fertilizers and Pesticides: Green Manure and Soil Improvement
Green leaves and leguminous plant material become manure that improves soil structure, water retention and protection from erosion.
Open article →Fertilizers and Pesticides: Biofertilizers and Microbial Nutrients
Biofertilizers contain living microbes that colonise roots or soil and make nitrogen or phosphorus more available to crop plants.
Open article →Fertilizers and Pesticides: Chemical Safety and Organic Farming
Chemical pesticides protect crops from pests but can harm other organisms, so safe use and natural organic-farming alternatives matter.
Open article →Fertilizers and Pesticides: Biopesticides and Bt Crop Protection
Biopesticides use living organisms for crop protection; Bacillus thuringiensis produces a protein toxic to susceptible insect larvae.
