Straight Fertilisers | Proctors NPK? ›

Straight fertilisers are those which only comprise of one of the three main nutrients; nitrogen, phosphorus and potassium, and can be very effective when encouraging your garden to grow to its full potential.

Straight fertilizer usually contributes one of these 3 main nutrients to the crops which are Nitrogen (N), Phosphorus (P) and Potassium (K) or mostly known as NPK. Nitrogen fertilizer – Nitrogen is one of the main elements which can be found in most commercial fertilizer.

Straight fertilizers: Straight fertilizers are those which supply only one primary plant nutrient, namely nitrogen or phosphorus or potassium.

For example, a 20-20-20 blend means that the fertilizer contains 20% nitrogen, 20% phosphorus, and 20% potassium. Another common blend is 16-20-18, which refers to 16% nitrogen, 20% phosphorus, and 18% potassium.

General fertilisers tend to have balanced NPK values (5-5-5 / 8-8-8), while specialized fertilisers will have a higher value of a specific macronutrient depending on the purpose.

Overuse of NPK fertilisers can lead to soil acidification, reduce biodiversity, contribute to the leaching of nutrients into waterways, causing eutrophication and water pollution, and release nitrous oxide, a potent greenhouse gas.

The advantage of a straight fertilizer is the low price compared to other fertilizers in the market. We offer several types of straight fertilizers contributing one of the 3 main nutrients to the crops, which are Nitrogen (N), Phosphorus (P) and Potassium (K) or mostly known as NPK.

The straight N fertilizers used in Zimbabwe are ammonium nitrate (AN), urea, sodium nitrate, ammonium sulphate (AS) and calcium nitrate. The straight phosphate fertilizers are single, double and triple phosphates. The potash fertilizers are potassium chloride (KCl) and potassium sulphate (SOP - K₂SO₄).

Nitrogen helps produce green leaves and stems, phosphorus helps produce root development, and potassium helps the plant withstand stress from heat or cold. A good all-purpose fertilizer would be a 10-10-10 NPK (nitrogen, phosphorus, and potassium).

Ammonium Nitrate is a straight fertilizer which provides nitrogen to the plant during the vegetative stage when it needs it most. Nitrogen gives leaves a deep green colour and in cereals it increases the plumpness of grain. It tends to also increase succulence in plants such as radishes and lettuce.

What is the perfect NPK ratio? ›

This additional production has, therefore, to come through efficient, judicious and balanced use of chemical fertilizer. A NPK ratio of 4:2:1 (N:P2O5:K2O) is generally considered ideal and accepted for macro-level monitoring of consumption of plant nutrients for the country as a whole.

NPK 20:10:10.

This type of fertilizer would be ideal for a plant that requires more Nitrogen, such as a leafy vegetable like spinach or lettuce. NPK 15:15:15 ratio represents a balanced fertilizer, with equal amounts of Nitrogen, Phosphorus, and Potassium.

A fertilizer listed as "10-10-10" is considered a balanced or "complete" fertilizer because its nitrogen, phosphorus, and potassium proportions are equal. Meanwhile, a fertilizer labeled "10-0-10" is an "incomplete fertilizer."

Tomato plants require enough phosphorus supply to ensure a healthy fruit set. It's usually present in water-soluble fertilizer formulas with NPK ratios of 24-8-16 or 18-18-21.

Because synthetic fertilizer is manufactured, it can be much more concentrated. These are fertilizers that are labeled 10-10-10 or even 20-20-20. Organic fertilizer is usually much lower in concentrations like 2-2-2 or 1-2-3. These fertilizers are commonly referred to as gentle fertilizer.

A typical analysis is NPK 1.7% nitrogen, 0.5% phosphates and 5.3% potash. Home made feed is likely to be less concentrated.

NPK fertilizers are mixed fertilizers containing Nitrogen, Phosphorous and Potassium(NPK) in different proportions, which are required for promoting plant growth and high crop yields.

Adding a sprinkling of the fertiliser to the hole before adding the tree will ensure the young tree has all the nutrients it requires to make a great start in life. Similarly, adding NPK 20 20 20 to vegetables shortly have they have been transplanted out will give them a boost and result in an abundant harvest.

The five basic straight fertilizers are: Easygro Potassium Nitrate. Easygro Magnesium Sulphate (epsom salt) Easygro Monopotassium Phosphate (MKP)

The correct answer is NPK fertilizer. Key Points. Fertilizers containing all three primary nutrients (nitrogen, phosphorus, and potassium) are called complete fertilizers. If high levels of phosphorus and potassium are already present in the soil.
