Why Does My Farm Or Garden Need To Be Fertilised?
- They need to be fertilised because most soil does not provide the essential nutrients required for optimum growth, as the plants grow, they absorb nutrients and leave the soil less fertile.
By fertilising their garden, you replenish lost nutrients and ensure that plants have the food they need to flourish.
- In farms, once crops are harvested for human consumption, the natural supply of nutrients in the soil must be “refilled”. This is why farmers add nutrients to their soil.
Nutrients can be added from a variety of sources—organic matter, chemical fertilisers, and even by some plants.
- This maintains soil fertility, so the farmer can continue to grow nutritious crops and healthy crops. But knowing which fertiliser to choose, how much to apply and which plants to feed is not always obvious.
Knowing The Plants’ Needs Makes All The Difference:
Landscape trees and shrubs - Don’t need fertiliser at all unless they’re showing signs of stress like yellowing foliage.
Annuals - Are Heavy feeders and should be fed weekly with a fertiliser.
Perennials - Don’t need fertiliser unless they’re showing signs of stress.
Vegetables - Need plenty of nutrients.
Fruit trees and berries - Heavy feeders and will be more productive if fertiliser is added at the right time.
Roses and Hydrangeas - Can benefit from more feeding than many other shrubs in the garden. You can find fertilisers labelled specifically for them.
Grass - Grass, in particular, needs extra macro-nutrients which can come from air and water, but which are used in such quantities that supplemental applications are beneficial. Commercial lawn fertiliser suppliers can supply you with the right kind of fertiliser for the right kind of grass.
Never, ever apply lawn fertiliser to your garden. The high nitrogen levels present in fertilisers meant for grass will burn the vegetables and cause an imbalance in the nutrient ratio.
All Pants Benefit From Basic Macro- And Micro-nutrients:
The main nutrients are nitrogen, phosphorus, and potassium.
A soil test is a great way to decide which of these ratios is needed in the highest amount.
The ratio of nutrients on any plant food is represented by N-P-K and states the amount of each.
Secondary nutrients and micro-nutrients are very important in facilitating many critical plant functions and in enhancing sugar translocation, root strength, and overall plant immunity.
The most critical of these micro-nutrients are Boron (B), Zinc (Zn), Manganese (Mn), Copper (Cu), Cobalt (Co), Molybdenum (Mo), and Sulphur (S).
Many micro-nutrients act as enzyme co-factors and building blocks that enable plants to build complete proteins and compounds.
They also aid in the development of larger, stronger roots and promote better plant immunity.
You can get Quality Micro-nutrient Products from farm fertiliser suppliers.
- Organic fertiliser ingredients are made from plant, animal or mineral sources.
- Examples are alfalfa meal, kelp, blood and bone meal, soft rock phosphate and green sand.
- Most organic fertilisers contain slow-release nutrients that will become available over time. They also contain many trace elements that might not be supplied by synthetic fertilisers.
- To build the long-term health and fertility of your soil, use granular organic fertilisers. Supplementing with a water-soluble fertiliser ensures that your plants have the nutrients they need when they're in active growth.
If you decide to use an herbicide to control weeds, be sure to select the appropriate product for your situation from your agricultural weed killer suppliers. There are hundreds of different herbicides on the market. Be sure to read, understand and follow all of the label directions when mixing and applying herbicides. In fact,
- Plants don’t care if they get nutrients from organic or synthetic fertilisers. It’s all the same to them.
- Fertiliser use is very expensive and can harm the environment if not used correctly.
- Therefore, before adding fertiliser, it is better to do soil testing. to know which nutrients, and how much to be applied? to the soil. If too little, crops will not produce as much as they should.
- If too much or at the wrong time, excess nutrients will run off the fields and pollute streams and groundwater.
So, while fertilisers serve an important purpose, farmers must be careful to use the right amount, at the right time, to avoid potential negative effects on the environment.
