LECTURA SOBRE USO DE BIOTECNOLOGÍA REDUCIENDO EL USO DE PESTICIDAS QUÍMICOS, HERBICIDAS Y FERTILIZANTES/ USE OF BIOTECHNOLOGY IN REDUCING THE USE OF CHEMICAL PESTICIDES, HERBICIDES AND FERTILIZERS
A lot of debate is going on the overuse of chemical herbicides, pesticides and fertilizers. They become an environmental hazard because they undergo degradation by …ver más…
Siderophores are iron-binding low molecular weight (400- 1,000 Daltons) peptides synthesized by some soil bacteria.
D) Organic fertilizers- Certain types of organic wastes are used as fertilizers e.g. animal dung (cow dung, elephant dung etc.), urine, urban garbage, sewage, crop residues and oil cakes. All these wastes can be converted in to organic manures.
Advantages of using biofertilizers
- Biofertilizers improve the tolerance of plants against toxic heavy metals.
- It is possible to reclaim saline or alkaline soil by using biofertilizers.
- Use of biofertilizers helps in controlling environmental pollution.
- Fertility of soil is increased year after year.
- Low cost and easy to produce.
- Biofertilizers increase the physico-chemical properties of the soil, soil texture and water holding capacity.
Some of the limitations encountered while using the biofertilizers are that they alone cannot meet the total needs of the plants for nutrient supply and also they do not produce the spectacular results as observed in synthetic fertilizers. It is important to evolve an approach which can maximize the use of biofertilizers and reduce the dependency on the chemical fertilizers in the near future with out affecting the crop productivity. This will help us to solve the environment related problems caused due to overuse of chemical fertilizers.
Una gran cantidad de debate que está pasando en el uso excesivo de químicos
