You might think that organic fertilizers, as opposed to the use of synthetic chemicals to fertilize the soil, are always a good thing. But there are certain disadvantages to using non-synthetic inputs if you don’t have the benefit of soil test analysis. For example, animal or biological wastes that are not properly composted might cause pathogens or organisms carrying diseases to spread. The nutrient content of your soil may be too deficient which may need to be corrected by chemical inputs.
Other Factors That Impact Effectiveness
Leaching is also another factor that negatively affects organic testing analysis inputs. Leaching is defined as the process when the essential plant nutrients and pesticides are washed away because of the texture and permeability of the soil. Organic inputs ordinarily have lesser nutrients and solubility which means they release nutrients faster to the soil in case of leaching. For example, as much as 60% of the nitrogen content of organic fertilizer is released through several leachings.
The industry of organic farming in South Africa is huge but it’s more of a necessity more than anything else. Yes, the costly chemical inputs may be out of reach for most farmers in that region but they also embrace the practice knowing its full benefits.
Finding the Right Mix
Achieving soil balance is the key to increasing yield. Without the guidance of the soil engineer and proper soil test analysis, you can’t just go into pure organic without stunting the growth of your plants. In fact, liquid sulphur is a chemical chelate that has been proven to be a good foliar and soil treatment product. It’s like feeding a baby, when you shore up too much on salt and sweets, the baby will likely become overweight. When you introduce vegetables and other nutrients into the diet, as well as some physical activity, the kid is going to grow up healthy.
One offshoot of soil test analysis is its chemical predictor potential. The water extract method identifies the presence of nutrients in the soil as well as the amount. This will give the farmer a lot of flexibility to know which inputs to purchase because plants only use what they need, the rest are discarded. This is also a cost-saving approach because you don’t have to buy fertilizers you don’t really need and thus ensure sustainability. The water extract method is also environmentally friendly because you don’t necessarily expose your field to a lot of chemicals.
