Welcome To 

Soil Science and Agriculture

    I am Lokesh Kumar Saini, completed my B.Sc. (Agriculture) from MPKV, Rahuri, M.Sc. (Agriculture), and Ph.D. degree in the field of soil science and agricultural chemistry from NAU, Navsari. 

Lokesh Kumar Saini

    Soil science and agriculture is an Educational Platform. Here I will provide you only interesting content related to agriculture, which you will like very much. I am dedicated to providing you the best educational blocks related to soil science, agriculture, pesticides, food safety, food quality, and other agriculture-related information. I am working to turn our passion for education into a booming online platform. I hope you enjoy our blogs as much as I enjoy offering them to you.

    I will keep posting more important posts related to soil science and agriculture on this platform for all of you. Please give your support and love.

Thanks For Visiting...

Have a nice day!

Phosphorus fixation in soil

Phosphorus fixation is the conversion of soil solution phosphorus to insoluble compounds by the soil components, causing a reduction in the amount that plants can absorb. Phosphorus availability is usually greatest in slightly acidic to neutral soil (pH 6-7). The amount and manner in which soluble phosphorus is fixed is influenced by the pH of the soil solution. Between pH 4.0 and 8.0, the main phosphate ions in soil are H 2 PO 4 - and HPO 4 2- . PO 4 3- predominates above pH 9.0, but H 2 PO 4 - is still present. The extent of problems of phosphorus fixation in India The efficiency of phosphatic fertilizers in India is around 15 to 20 percent because of their fixation in acidic and alkaline soils, and unfortunately, both soil types lead in India, accounting for more than 34% acidity affected and more than 7 million hectares of productive and fertile land salinity/alkalinity affected. Phosphorus fixation is greater in black, red, laterite, mixed red and black, red and yellow, and coast...

Nutrient deficiency and toxicity disorders in plants

Nutrient deficiency and toxicity disorders in plants 1. Nitrogen (N) Deficiency: Buttoning in cauliflower  Toxicity: Hollow stem in cauliflower 2. Phosphorus (P) Deficiency: Sickle leaf disease 3. Potassium (K) Deficiency : Yellow white mottling of cotton Firing of tobacco leaves Toxicity : Blotchy ripening of tomato (K excess & N imbalance)  4. Calcium (Ca) Deficiency : Blossom end rot in tomato Bitter pit in apple Pillow diseases of cucumber Die back disease of pea  5. Sulphur (S) Deficiency : Tea yellow diseases   6. Magnesium (Mg) Deficiency : Reddening of leaves in cotton Sand drawn diseases in tobacco Grass tetany (animals)   7. Iron (Fe) Deficiency: Papery white (complete whiteness of leaves) Yellowing of groundnut White eye of rice Leaf bleaching in sugarcane Ivory white of paddy Toxicity: Browning of   rice Bronzing in leaf blade rice (>300 ppm) 8. Manganese (Mn) Deficiency: Sugarcane blight Pahlala blight of sug...

Green Chemistry: Adoption and Implementation Approaches in Agrochemical Sector

       Anastas coined the term "Green Chemistry" for the first time in 1991, in a special program created by the US Environmental Protection Agency (EPA) to stimulate significant development in chemistry and chemical technology. The program also aimed to change chemists' perspectives on environmental protection by focusing on lower risks or their complete elimination in terms of human health. Green chemistry is a chemical research and engineering philosophy that involves the development of products and processes that reduce the use and generation of hazardous chemicals (Pereira, 2020). Unlike environmental chemistry, which studies pollutant chemicals and their effects on the environment, green chemistry seeks to reduce pollution at its source. Green chemistry entails reducing waste at the source, using catalysts instead of reagents, using non-toxic reagents, using renewable resources, increasing atom efficiency, and using solvent-free or recyclable environmentally fr...
