What fertilizers to apply in spring: signs of deficiency and help in choosing

For most crops, spring fertilization is of such importance that it is difficult to overstate it. There are exceptions when the soil is prepared in advance.

However, this is not important. It is important to add in the spring exactly those additives that the soil and plants need, and therefore you need to learn to distinguish the signs of a fertilizer deficiency.

There is no need to conduct any chemical analysis. It is enough to observe the weeds or remember which of them were rampant in the beds during the past summer cottage season.

Nitrogen deficiency

In this case, legumes, as well as clover, sedum or sundew, will grow at full capacity.

Calcium deficiency

This is a comfortable environment for heather, ferns and even violets.

Potassium deficiency

Plantain will be present in abundance.

Phosphorus deficiency

In such conditions, sorrel grows, and the only berry plants are blueberries, cranberries and lingonberries.

What to contribute

1. Of the organic additives, humus is added in the spring (once every 3 years), but this is more often done in the fall. If the manure is fresh, it is better to wait, otherwise the fertilizer will cause burns.

Instead of manure, you can sow green manure: legumes, cereals, cruciferous plants.

Also used from organic matter are wood ash, herbal infusions, compost, peat, sapropel, eggshells, etc.

2. Mineral fertilizers used are primarily nitrogen (urea, ammonium sulfate or ammonium nitrate); potassium (saltpeter, potassium magnesium sulfate, sulfate), and also superphosphate.

3. Complex fertilizers are a simple alternative. Summer residents have long loved nitrophoska, diammophoska, ammophoska, etc. Fertika, Poligro-universal, Gumat-iodine, Micro-mix and other compositions marked "spring" are also used.
