Although there may be adequate potassium in a normal soil, it is only slowly available, and is easily washed out of the soil, so additional applications of potassium are necessary. A phosphorus deficiency is shown by poor germination of seeds, slow growth of plants, and poorly formed roots. SR fertilisers have the following advantages: These are balanced fertilisers that are applied in solution to the foliage of plants. It is well known that soluble organic and inorganic fertilisers sprayed onto the leaves of most plants are more readily absorbed by the plants, resulting in quicker growth in contrast to fertilisers being absorbed through the roots.

South Africa based we have been trading for over 20 years. Too much phosphorus in the soil is very rare; it shows in the form of stocky growth with small buds and flowers. The salient characteristics of fertilizer use in Sub-Saharan Africa (SSA) are (1) the extremely small quantities of both organic and inorganic fertilizers used, (2) the very low intensity (kg/ha) of use, and (3) the slow rates of growth in fertilizer consumption. With agricultural demand increasing, fertilizer consumption is continuously rising. The Fertilizer Society of South Africa was established in 1959. Fruit and vegetables are poorly coloured and lack flavour. Phosphorus also influences the uptake of potassium in plants.

An adequate supply of phosphates in the soil also offsets the adverse effects of too much nitrogen in the soil. Potassium sources include manure, woodash and Condi's crystals. However, not all plants will respond the same, and it is usually soft-leafed plants that show the quickest response. Foliar fertilisers are recommended particularly for plants under trees, to make sure that the plants, and not the tree, absorb the fertiliser. 0000002535 00000 n 0000005897 00000 n There are two main types of slow-release fertilizers: water-soluble nitrogen fertilizers (WSN) and water-insoluble nitrogen (WIN), available for specific applications. Nitrogen is released by biochemical action, thereby providing nitrogen in a highly acceptable form as and when the plant needs it. %PDF-1.3 %âãÏÓ There is normally a large amount of phosphorus in the soil, but only small amounts at a time are available to the plants. The first systematic field calibration work, with field trials on the response of cereals to applied nutrients, was initiated in the early 1970s by the Department of Agriculture, Cedara (Farina et al., 1992), with maize as the first test crop.

Fertilizers are used for various purposes. Potassium is also necessary for root crops, where it is stored as starch. Potassium is essential to plants for photosynthesis, the vital process by which plants make food for growth. Sandy, light-textured soils need more frequent fertilising than clay soils because leaching of chemicals is faster in sandy soils. DEFINITION: Average fertilizer use (kg per ha of cropland 2000). They lack nutrient-holding elements such as clay and humus particles, so nutrients are leached out of the soil fairly quickly by water, be it natural rainfall or artificial watering. Sand Lime Bricks 0000002355 00000 n Wholesale Fertilizer / Plaas Kunsmis. It is therefore especially beneficial to leafy vegetables, such as lettuce, spinach and cabbage, and to lawns which are constantly being mown. South African soils generally tend to be low in nitrogen. Choosing a fertiliser is not a difficult matter, as long as you remember that the most important and vital chemicals for plant growth are nitrogen (N), phosphorus (P) and potassium (K). Nitrogen-fixing bacteria in the soil. 0000004129 00000 n Lack of nitrogen in your soil will show clearly by yellowing of leaves and stunted growth of all plants including vegetables. To compensate, soluble forms of phosphorus fertiliser should be added. Life is a Garden is the marketing division of The South African Nursery Association (SANA). Case studies from other developing countries in South Asia and South America were also be referred to where relevant. Compounds are chemically processed to have all the specified units in one granule, while blends are a physical mixture of different minerals and nutrients in customized proportions. Nitrogen-rich fertilizers are used for the greening of lawns. The nitrogen in these fertilisers will not be leached from the soil quickly, so slow-release fertilisers need not be applied as often as the non-slow release ones. Nitrogen (N) is the most important of the plant foods. If the three numbers are followed by the letters SR, this means that the fertiliser is a slow release fertiliser, which will supply the chemicals to the soil over a period of time, and not all at once. Nitrogen fertilizers Nitrogen fertilizers contain nitrogen that crops need during development. 17 0 obj << /Linearized 1 /O 19 /H [ 962 241 ] /L 31759 /E 10022 /N 5 /T 31301 >> endobj xref 17 28 0000000016 00000 n These GCA garden centres can be identified by yellow and green GCA flags, present at garden centres and home stores, nationwide. in a 37 percent fall in the use of phosphate fertilizers, compensated, but only in part, by a gradual but steady increase in nitrogen use. 0000008657 00000 n 0000006813 00000 n If you apply too much fertiliser, plants are unlikely to be 'burned' by excess nitrogen. According to statistics, fertilizer use in South Africa is urea, ammonuim sulphate, mono-ammonium phosphate, calcium ammonium nitriate and diammonium phosphate. However, if too much nitrogen is applied, it will lead to soft, lush growth, which renders the plant susceptible to damage by cold, fungal disease and insect attack. Nitrates (the form of nitrogen used by plants) come from various sources: Phosphorus (P) stimulates early root formation and germination of seeds.
