Fertilizing when planting tomatoes


Not every gardener knows what to put in a hole when planting tomatoes, but it is the planting-in fertilizer application that can have a positive effect on both the quantity and quality of the crop of such a vegetable crop as tomato.

What to put in a hole when planting tomatoes to increase productivity

When planting any vegetable crops, including the cultivation of tomatoes in open or closed ground, fertilizer plays a very large role and allows you to get maximum productivity with minimal time and effort.

Thus, one of the principles of increasing the overall productivity of tomatoes without increasing the landing area, as well as to improve the quality characteristics of the resulting vegetable products, is rational and timely use of mineral fertilizers in accordance with the following recommendations:

  • in order to increase the yield of vegetable crops and improve the physico-chemical characteristics of the soil, it is necessary to systematically apply fertilizers in conjunction with processing and irrigation;
  • well-cultivated soil helps to increase the overall yield and improves the commercial value of vegetables, including sugar content, protein and dry matter content, the amount of vitamins and minerals;
  • to get the highest quality tomato fruits, a balanced mineral nutrition of plants should be preferred, and optimal doses of fertilizers can provide an increase in the yield of this vegetable crop.

How to use ash as a fertilizer

For each ton of fruits of highly productive tomato varieties, the following amount of nutrient components should be accounted for:

  • nitrogen - about 3 kg;
  • phosphorus - about 1 kg;
  • potassium - about 4 kg.

In the process of growth and development, a vegetable culture such as tomato is characterized by increased absorption of potassium-phosphorus components, the introduction of which allows you to get earlier and more abundant flowering. At the same time, after planting seedlings at a permanent place of cultivation, it is advisable to introduce nitrogen-containing complexes that can stimulate the growth of vegetative mass.

All fertilizers introduced under tomatoes can be attributed to three main groups:

  • organic fertilizers;
  • fertilizers of mineral type;
  • fertilizers of a bacterial type.

The most effective is the local application of granular superphosphate when sowing seeds. If we plant tomato seedlings, it is recommended to add phosphate fertilizers in the autumn. In this case, when digging the soil, fertilizers are put in the form of simple, granular, double or ammonized superphosphate.

A lack of potassium in the soil entails a decrease in the intensity of photosynthesis processes, and also reduces the level of resistance to fungal infections, so with deep preplant digging, it is advisable to add potassium nitrate or potassium sulfate. You can also put organic, which improves the structural parameters of the soil and serves as an excellent nutrient base for garden crops. If seedlings are planted and two are grown in the same well, the dose of fertilizer should be increased by 50%.

The best finished products

Currently, domestic and foreign producers produce a large assortment of fertilizers that meet all safety requirements and allow you to get not only a high, but also a high-quality tomato crop. Fertilizing with such fertilizers is not difficult and should be carried out in accordance with the manufacturer's instructions.

High-grade mineral fertilizer "Kemira-universal-2"Nitrogen, phosphorus, potassium, magnesium, sulfur, iron, boron, copper, manganese, molybdenum and zincIn the spring dig evenly pour on the landing area with a flow rate of 150−160 g / m2 or use local application of full mineral fertilizer and put it directly into the planting holes
Complex type of organic mineral chlorine-free granular fertilizer "Universal"Fertilizer based on humic compounds, nitrogen, phosphorus, potassium, magnesium, sulfur, iron with the addition of zinc, copper, manganese, molybdenum and boronIt is introduced during the pre-planting digging of cultivated and uncultivated soils at the rate of 100-150 g / m2or in a hole followed by mixing with soil
Magnesium Sulfur Fertilizer "Magnesium Sulfate"The main components are 16% magnesium and 13% sulfurIt is introduced during the pre-planting digging of cultivated and uncultivated soils at the rate of 12-15 g / m2

Also, from ready-made fertilizers for planting tomatoes, one can recommend the introduction of superphosphate, nitroammophos and organic additives in the form of peat, humus and manure.

How to plant tomatoes

Popular folk remedies

Most often, when preparing soil for planting tomatoes by domestic gardeners, the following folk remedies are used:

  • wood ash, which is a source of potassium and phosphorus, as well as magnesium, sulfur, zinc and others, the most important for the growth and development of garden crops, trace elements, the standard consumption of wood ash when applied locally to the planting holes is about three tablespoons per plant;
  • Strait of planting holes with yeast fertilizer prepared at the rate of 20 g of yeast per bucket of warm water has good efficiency;
  • The best option for high-quality pre-planting soil preparation at the tomato growing site is composting during deep digging of the soil in spring.

It is very important to remember that from organic fertilizers it is best to add rotted manure or humus for tomatoes, as well as peat compost, manure and bird droppings. However, fresh organic matter can only be applied on poor in composition soils.

Tips & Tricks

Proper fertilizing at the stage of pre-planting preparation of a site for growing tomatoes is a guarantee of a high and high-quality crop. Experienced gardeners and amateur vegetable growers recommend fertilizing according to the following technology:

  • the introduction of dolomite flour at the rate of 100-150 g per square meter, followed by a uniform distribution of fertilizer throughout the planting area;
  • the introduction of superphosphate at the rate of 50–80 g per square meter of landing area;
  • the introduction of a full-fledged complex mineral fertilizer at the rate of 50 g per square meter of landing area.

What fertilizers to apply in the autumn in the soil

The final stage of fertilizing is the thorough mixing of the nutrient composition with the soil, which will protect the root of the plant from getting burns. Before making the application of ready-made or self-made fertilizers, it is very important to carefully read the instructions supplied by the manufacturer, as well as take into account fertility indicators and soil composition.
