What is organic farming?

Organic farming is the form of agriculture that depends on techniques like crop rotation, green manure, compost, and biological pest control. An organic farm is a farm whose structure is formed in imitation of the structure of a natural system that has the integrity, the independence, and the benign dependence of an organism.  

Specific of organic farming:

1.    Organic farming uses fertilizers and pesticides but prevents the use of manufactured or synthetic fertilizers, herbicides, insecticides, and fungicides.
2.    Organic farming excludes using genetically modified organisms.
3.    Organic agriculture is a production system that sustains the health of soils, ecosystems, and people.  
4.    Organic agriculture relies on ecological processes such as biodiversity, and cycles adapted to local conditions, rather than the use of inputs with adverse and unfavorable effects.
5.    Organic agriculture combines tradition, innovation, and science to benefit the shared environment, promote fair relationships and the good quality of life for all involved.
6.    Many kinds of organic farming were the original type of agriculture and have been practiced for thousands of years.

Forest gardening

  1. An organic food production system which dates since the prehistoric times is the world’s oldest and most concordance and resilient with agro ecosystem. 
  2. After the industrial revolution had introduced inorganic matters as fertilizers, pesticides, herbicides, and fungicides many of these substances had serious side effects. 

Soil management:

1.    Plants need nitrogen, phosphorus and potassium as well as micronutrients and symbiotic relationships with fungi and other organisms to flourish and grow healthy.
2.    Likely greatest challenges for organic farmer are getting enough nitrogen for his plants at the right time.
3.    Rotation and green manure help to provide nitrogen through legumes which fix nitrogen from the atmosphere through symbiosis with rhizoidal bacteria.
4.    Intercropping that is many times used for insect and disease control, can increase soil nutrients.
5.    Competition between the legume and the crop may cause some problems; therefore wider spacing between crop rows is required.
6.    Crop residues can be ploughed back into the soil; different plants supply different amounts of nitrogen.
7.    Organic farmers use also animal manure, certain processed fertilizers like seed meal and various mineral powders such as rock phosphate and green sand, which provides potassium, these methods help to control erosion.
8.    PH may need to be amended.
9.    Natural amendments of PH include lime and sulfur.   

Farms with both livestock and crops

  1. Farm consisted of livestock and crops can operate more easily. 
  2. Whereas the land gets fertility through growing nitrogen fixing forage grasses such as white clover or alfalfa and grows cash crops or cereals while fertility is established.

    Stock less farms

    1. Or those without livestock find more difficulties to maintain fertility. 
    2. And should rely more on external inputs like imported manures as well as grain legumes and green manures.  
    3. Horticultural farms.
    4. Growing fruits and vegetables are even more reliant upon external inputs.

    Organic farming beneficial:

    1.   Varieties of bacteria and fungi break down chemicals, plant matter, and animal waste into productive soil nutrients.
    2.    By the way, they produce benefits of healthier yields and more productive soil for future crops.
    3.    Fields with no or less manure display lower yields due to decrease soil microbe populations then render more arable soil system.
