The continuous rise in the price of fertilizers, combined with side effects and harmful diseases with synthetic fertilizers. Conventional farmers and organic farmers share a need for a low cost, highly efficient source of nutrition for their crops.
According to the trend, organic fertilizers are becoming the first choice for many people. Widely used for vegetables (tomatoes, lettuce, cucumber), fruits (strawberries, grapes, citrus), Cash crops (grass, flowers, cannabis)
Many of the Organic fertilizers that meet organic certification may also work for conventional farmers who are looking for a low-cost, readily available source of N-P-K for their farms.
What is N-P-K?
- The three numbers on fertilizer represent the value of the three macro-nutrients used by plants. These macro-nutrients are Nitrogen (N), Phosphorus (P) and Potassium (K) or NPK for short. The higher the number, the more concentrated the nutrient is in the fertilizer.
- For example:- Numbers on fertilizer listed as 20-5-5 has four times more nitrogen in it than phosphorus and potassium. A 20-20-20 fertilizer has twice as much concentration of all three nutrients than 10-10-10.
Two broad choices are available for conventional growers, organic and synthetic. For organic farmers, only the organic option is available. Organic farmers can and do use composts of plant and animal materials and un-composted plant materials are allowed under Federal NOP (National Organic Program) guidelines. Raw manure can be used but must be applied at least 120 days prior to harvesting most crops.
Organic Fertilizer Definition
Organic fertilizer is also called “farm manure”. It refers to compost made from animal waste or animal and plant residues that are rich in natural by-products. For example, guano, dried and powdered blood, ground bone, crushed shells, finely pulverized fish, phosphate rock, and wood.
The methods for Organic farming and the use of fertilizers.
Type of Organic Fertilizer
Organic Fertilizers are different types of fertilizers. They are derived from vegetable matter, mineral matter, animal matter, etc. Here are some of the most common of organic fertilizers:
Best Plant-Based Fertilizers
Compost is rich in nutrients. They can be used as an excellent soil improver to promote organic matter and soil fertility. It is very good for terrace Gardening.
- Cottonseed Meal
Cottonseed Meal is a rich source of nitrogen and a small amount of phosphorus and potassium. It can be an excellent organic fertilizer grass.
- Alfalfa and Soybean meal
It contains nitrogen, phosphorus, and neutral pH.
Soybean meal is a functional additive for longer-lasting results during soil maintenance.
Seaweed is an immediate-release fertilizer and an excellent source for zinc and iron. It goes well with the high-potash crop.
Best Animal-Based Fertilizers
- Bone Meal
Crushed animal bones are the main components of bone meal. It’s rich in phosphorus and calcium and supplies some nitrogen. It can promote plant seedling growth, help flowers grow, and increase yield.
- Blood meal
It acts as a natural pest repellent for the plant. A blood meal is a dried form of animal blood. It can improve the nitrogen content in the soil and makes the plants denser. Release nitrogen quickly promotes flowering and acts as a natural pest repellent.
- Animal Manure
There is a variety of animal manure. For example, cow manure can control weeds and increases the moisture-holding capacity of the soil and increases air penetration in the soil.
Seabird guano is an organic fertilizer for lawns. It can act as a natural fungicide and control nematodes in the soil.
- Fish meal
Fish meal is a fast-release fertilizer that is a rich source of organic nitrogen, phosphorus, and calcium. It can improve soil health, increase fertility, and make plants thrive.
This blend of finely ground, decomposed fish delivers a big dose of nitrogen. Acts as a soil conditioner. But be careful. Fish Emulsion is highly acidic, and overuse can burn plants.
Shellfish are made from the broken shells or bones of shellfish and crabs. The organic fertilizers made from this are rich in calcium.
Organic gardening emphasizes cultivating your garden to maintain fertile soil, plants, and beneficial insects. W can achieve this if we avoiding the use of synthetic fertilizers and pesticides. Also by using products that nurture the garden soil and the organic matter in it.
When you adopt the concept of organic fertilizer, your plants and crops will experience a balanced, nutrient-rich ecosystem that can work according to natural expectations.
