They release their nutrients more slowly in the soil, when the plants need them, so they last longer.
They enhance soil health by nurturing (or at least not harming) the soil microbes that help make soil nutrients and nitrogen available to plants.
They reduce acidity in the soil.
They help improve the structure of the soil including the circulation of air, which sustains beneficial microorganisms that help release nutrients to the soil.
Fact 1: NPK - NPK stands for Nitrogen, Phosphorous and Potassium. The German scientist Justus Von Liebig came up with the theory that Nitrogen, Phosphorous and Potassium are mainly responsible for healthy plant growth.
Fact 2: Poultry manure has the highest amount of Nitrogen, Phosphorus, and Potassium.
Fact 3: Chicola Organic Fertiliser comes from poultry manure.
Fact 4: Plants are just like you and me. Plants need nutrients just like us humans. The main nutrients they need, as stated above, are Nitrogen(N) for stem and leaf growth, Phosphorus (P) for root growth and photosynthesis, and Potassium (K) for fruit and flower growth. All plants need all three, but leafy crops particularly need nitrogen, and fruit crops won't develop well without enough potassium. They of course also need other nutrients, though in tiny quantities.
Fact 5: Plants need bacteria and fungi in the soil to break it down and release food to their roots, just as we need bacteria to digest food. Organic fertilizer such as our product Chicola, unlike chemical fertilisers, support microorganism in the soil such as bacteria and fungi.
Fact 6: Nitrogen deficiency results in older leaves turning yellow with new growth being weak and spindly. Nitrogen is responsible for the strength and vigour of your plants. Phosphorous deficiency would include poor germination and establishment of seedlings, mature plants showing stunted growth and dark blue/green leaves or reddish-purple stems or leaves. Potassium deficiency results in yellow areas along leaf veins and leaf edges. Fruits like tomatoes may be stunted and lacking in flavour.
Differences Between Organic and Chemical Fertiliser
PHYSICAL PROPERTIES: ORGANIC FERTILIZERS
- Improves the soil structure
- Improves water holding capacity
- Soil becomes more permeable (improves pores or openings that permit liquids or gases to pass through).
- Improves drainage in the soil
- Prevents soil erosion
- Decreases water evaporation
- Humidifies the soil
PHYSICAL PROPERTIES: CHEMICAL FERTILISERS:
- No effect on soil structure
- No improved water holding capacity
- No effect of fertilizer on permeability
- Does not prevent soil erosion
- Does not improve drainage in the soil
- Does not decrease water evaporation
- Does not humidify the soll
CHEMICAL PROPERTIES: ORGANIC FERTILISER
- Slow release of nutrients
- Decreases leaching of nutrients from soil
- Supplies micronutrients
- Doesn’t produce acidity or alkalinity in the soil
- Upon decomposition produces organic acids while helps to dissolve minerals
CHEMICAL PROPERTIES: CHEMICAL FERTILISERS
- Fast release of nutrients
- Does not decrease leaching of nutrients from soil
- No micronutrients supply
- Fertilizers like sodium products produce acidity and alkalinity in the soil
- Does not produce organic acids
BIOLOGICAL ACTIVITIES: ORGANIC FERTILISERS
- Increases the growth of microorganisms like earthworms
BIOLOGICAL ACTIVITIES: CHEMICAL FERTILISERS
- Does not help the growth of microorganisms
USE: ORGANIC FERILISER
- Organic manures are incorporated in soil
USE: CHEMICAL FERTILISERS
- It is also incorporated in soil but may be used as top dressing
