Explanation of the significance of the nutrients N, P, K for plant growth
Nutrients N, P, K main control for overall plant growth
1. Detailed explanation of the benefits of nutrients N, P, K on plant growth
2. Characteristic plants when nutrient deficiency of N, P, K
Explanation when only relying on chemical fertilizers
1.1 Chemical fertilizers are very susceptible to evaporation
1.2 Easily absorbed by the weeds (weeds)
1.3 Chemical fertilizers are very easily washed away by rain, especially when very heavy rainfall and sandy soil texture tends
1.4 Some fertilizers are bound by the soil so it can not be absorbed by plants
1.5 NPK only provide macro nutrients, micro-nutrients while relying only on the ground
1.6 The structure of the soil will be more solid ground so that air circulation is hampered nutrients can not be absorbed by plants
1.Resulting from the use of chemicals in agriculture
Excessive use of pesticides to kill pests but add one other pest populations, pest- plant will resistant also chemicals that are more difficult to eradicate
Because chemicals are easy to get stuck in the ground to make the soil particles louder
The chemicals can also be deadly microorganisms and soil makroorganisme
Residues of chemicals can also be left in the plant, so it is very dangerous if consumed by humans continuously
1. One solution to reduce dependence on chemical fertilizers is to use organic fertilizers
2. Organic fertilizer will improve the soil chemistry in the form of nutrient , the soil physics and the structure of in the form of loose soil texture, and soil biological form makroorganisme & microorganisms soil.
3. using organic fertilizers soil fertility will be maintained so that the system will remain sustainable agriculture
Description of the two types of fertilizer known as organic fertilizer
Organic fertilizers are derived from the remains of plants and animals for example, is compostable
Biological fertilizers derived from soil mibrobia example is Feng Shou
Types of microbes is in Feng Shou is flagship microbes that have benefits to help provide N, P, K
There are also types of microbes that serve as plant growth hormones
Microbes that as microbial pesticide residues breaker
Microbes that serve as bioinsecticide
5. Microbes that serve as a degrading cellulose
