Botanicals, cultivational practices, mechanical means, and natural enemies are controls that are used in organic farming instead of chemicals. Parasites, pathogens and pests can attack organically grown edibles and ornamentals. But the inputs, methods and resources need to be animal- and plant-based, local, natural, non-genetically modified, non-synthetic and on-site in order for farming to be considered organic, not conventional.

∙ 12y agoSynthetic nitrogen, phosphorus and potassium are chemicals used as fertilizers of plants and soils.
Specifically, chemicals in fertilizers are artificially made minerals. Nitrogen, phosphorus and potassium can be accompanied by other synthetic nutrient and non-nutrient ingredients in commercial fertilizer. But they dominate as the big three macronutrients of fast growth and high yields.

∙ 7y agoBat and bird guano, blood-meal, bone-meal, chicken-feather meal, composted chicken manure, dehydrated cow-manure pellets, fish meal, green-sand, kelp, liquid seaweed and rock phosphate are examples of natural fertilizers used by organic farmers. Natural fertilizers may be considered longer in impact, more balanced in nutrients and slower in release than agro-industrial, chemical, commercial, conventional, intensive, synthetic fertilizers. They will not stress nitrogen, phosphorus and potassium at the expense of other macro-nutrients such as calcium, magnesium and sulfur or micro-nutrients such as boron, chlorine, copper, iron, lead, manganese, molybdenum and zinc.

∙ 7y agoNo chemicals are used in organic farming. Organic farming guidelines and inspections do not allow chemicals, genetic modification, growth hormones or synthetics. Organic alternatives to chemicals include botanical controls derived from animal and plant matter, such as the active ingredient pyrethrin from Chrysanthemum cinerariifolium, horticultural oils, insecticidal soaps, and natural enemies.

What are the uses of the chemicals in fertilizer?
The chemicals used in man-made fertilizers are meant to replace and react with the chemicals in the soil that are beneficial to the growth of Plants.
Evaluation on the use of inorganic fertilizers on the environment and humans?
Inorganic fertilizers are used to improve the production of cereals and other edible plants. They also can improve the quality of soils. But the abuse or incompetent use of fertilizers must be avoided; pollution of the environment is the consequence.
What are the differences between soil fertility and soil productivity?
The difference between soil fertility and soil productivity is that soil fertility involves the soils and fertilizing them per the types of plants, crops, and soils, being used. The soil productivity has to do with the drainage of the soils, the amounts and types of fertilizers, and the progress of the plants and crops due to fertilization.
Why are chemicals used in hydroponics?
Hydroponics are growing plants in a slightly sloping tray, where only their roots reach the water gently flowing over the tray's bottom. The chemicals, as in the question, are the nutrient that plants need for growth. If these nutrients was not added to the water, the plants would not thrive.
Will additional fertilizers, such as nitrogen supplements damage most plants?
The use of nitrogen and other fertilizers will enhance the growth of most plants when used correctly.
What chemicals harm plants?
It depends on the chemical. Fertilizers help them grow, defoliants and herbicides kill them, ethylene acts as a hormone, salt changes the osmotic balance, water is essential for plant life, carbon dioxide is used to manufacture food.
What do fertilisers do to help to environment?
Fertilizers are used to increase the production in agriculture; but the irrational use can lead to the pollution of soils and waters.
Can chemical fertilizers be used in plants?
Yes - they are used all the time by gardeners
What is the effect of fertilizers and manures used in plants?
the plants grows well and it will not last long after the yield
Why are fertilizers used for the plants?
to make them healthy and help them to grow bigger
What can animals wastes and fertilizers make?
It can be used to to help plants grow.
What precautions must gardeners take for chemical fertilizers to stimulate plants without damaging roots with too high concentrations?
Conducting soil pH tests, following label instructions, and matching correct fertilizer with correct plant are precautions which gardeners must take for chemical fertilizers to stimulate plants without damaging roots. Fertilizers do not benefit plants if the soil pH is too acidic or alkaline for the plant or if aeration and water pore spaces are insufficient or non-functioning in soils. With adherence to the label's directions in terms of application and timing, chemical fertilizers will do their job correctly as long as they are appropriate for the plant: for example, ericaceous fertilizers must be used with acidic soil-loving plants.
