There are numerous reasons for agriculture contaminants without direct application on plants . some are mentioned below-
1. Organic cultivation with hybrid inorganic mother seed : hybrid mother seeds are coated with insecticides .
2. Polluted surface and ground water for agriculture : plants absorb contaminants present in polluted ground and surface water . As per CPCB seven rivers of Himachal Pradesh are critically polluted .When it rains, water interacts with these toxic chemicals which then leach into groundwater sources or washed into the nearby waterways. Consequently, the
chemicals contaminate waters and the soils, and soil microorganisms plus beneficial insects are killed.
3. Buffer zone : buffer zone is an area located between a organic production operation and an adjacent land area that is inorganic to prevent contact by prohibited substances applied to adjacent land areas .
Most of the organic agro producers unwilling to spare a buffer land for organic cultivation .
4.However much animal manure and fertilizers are not directly toxic, they usually contain excess chemical nutrients especially phosphorus and nitrogen. They make up the main causes of nutrient pollution from agricultural sources.
5.Manures and Biosolids frequently contain nutrients including nitrogen, carbon, phosphorus . Furthermore, because they are industrially processed, they may also have within them contaminants such as personal care products (PPCPs) and pharmaceuticals. These products have been found in human and animal bodies and are believed to have negatively health impacts to wildlife, animals, and humans. Agricultural pollution becomes even harder to manage with such types of organic contaminants.
6.Livestock alone are substantial contributors to agricultural pollution. The feeds and unnatural diets fed to livestock are significant
sources of greenhouse gases and nutrients from excretory waste. Nitrogen-based compounds such as nitrogen and ammonia are potential sources of gaseous emissions.
7. Heavy metals : The primary agricultural inputs including pesticides, industrial by-product wastes, some fertilizers, and specific agrochemical products contain traces of heavy metals such as arsenic, cadmium, mercury and lead. When these substances accumulate in the soil or waste dump, they can be washed into waterways or leach into ground water sources or get absorbed by plants .
Invasive pests, weeds, and diseases do not directly cause agricultural pollution. However, because of the persistent and growing number of pests, weeds, and diseases which can negatively impact crop yields, farmers resort to the persistent use of pesticides, herbicides, and other agro-chemicals to combat this nightmare. As a result, increased uses of these chemical products persist in destroying the soils, animals, plants, waters, and wildlife based on the agricultural pollution intricacies,
Why not go for USDA / NOP organic certificate , only through SGS ?!
TC ( transaction certificate is mandatory for export consignment )
USDA ( packing ) certificate is also mandatory .
