Negative & Positive Effects of Pesticides & Fertilizer. Whether you're trying to tend to a healthy lawn, grow a few vegetables or manage an entire farm, the use of pesticides and fertilizer is an. Temperature, light, moisture, bacteria, pH, etc., all affect pesticides in different ways and cause them to break down at varying rates. The point is, pesticide breakdown, thus half-life, is dependent on many and varying factors when applied under normal use conditions. Some pesticides are more stable than others under the same conditions. Repeated exposure of pesticides cause insect resistance and affect the natural beneficial insects that help to decrease population of insect pest naturally. Fertilizers Fertilizers are any substance used to add nutrients to the soil to increase soil fertility and plant growth. In recent years, the use of fertilizer increase and cause serious. The use of chemical fertilizers on crops can have adverse effects on waterways caused by chemical run off of the excess fertilizer. The over-abundance of nutrients in the water reduces the amount of oxygen. The existing organisms living in the water use up the oxygen that is left. The result is oxygen depletion causing the fish to die.
The research took place in Van Yen district, Yen Bai province, one of the poorest provinces in the Northern Mountainous Regions of Vietnam (World Bank, ).Yen Bai's per capita GDP in was estimated at $ compared to the national average of $ ().The district covers km 2 and comprises of three economic regions: the rice intensification . Excessive Use of Fertilizers and Pesticides: Fertilizers are indispensable for increasing food production but their excessive use has occasioned much concern as a possible environmental threat. Excessive use of fertilizers is causing an imbalance in the quantity of certain nutrients in the soil. This imbalance adversely affects the vegetation. The soil testing along with plant analysis gives the true status of plant nutrients affected by soil properties to take the proper care for the plant growth. Our available water resources are diminishing and getting polluted with excess use of fertilizers and pesticides which are ultimately affecting the environment, food produced and water. affecting the realisation of organic potential in the north east hilly region as a KVK officers from ICAR-RC-NEH Region, Meghalaya. application of any synthetic fertilizers and pesticides and.
How do chemical fertilizers and pesticides affect our Food and Life. As we all know that today most of the farmers use pesticides and synthetic fertilizers to get a good crop production. As we all know that pesticides are come in wide varieties like insecticides, weedicides, herbicides, fertilizers, fungicides and many more. use of synthetically produced fertilizers, pesticides, growth regulators and livestock feed additives and rely on biological process such as crop rotation, organic manure, green manuring, bio-pesticides etc. The principle elements for success of organic agriculture are- . Fertilizers and pesticides both have definite pros and cons associated with their use. Both types of chemical tend to increase yields, and thus make a significant difference in food production, particularly in countries that struggle periodically with famines. On the other hand, they both can cause water pollution when erosion carries the. Fertilizers and pesticides 1. FERTILIZERS AND PESTICIDES PREPARED BY ZAHIRUDDIN ANSARI 2. FERTILIZERS A fertilizer or fertiliser (in British English) is any material of natural or synthetic origin (other than liming materials) that is applied to soils or to plant tissues (usually leaves) to supply one or more plant nutrients essential to the growth of plants.
