Types of organic fertilizers

a)      Peat

The best organic fertilizers include peat, in particular, lowland. In composition, it closely resembles compost as it also consists of dead plants. In lowland peat, approximately half of the mass is carbon. A feature of this organic fertilizer is that the chemical processes of formation occur under a layer of water.

So, the biomass is isolated from the air, and all substances remain in the composition but do not evaporate. Peat is excellent for restoring humus – the top fertile soil layer. The effect of the introduction will be noticeable only after 2-3 years.

b)      Manure

Organic nitrogen fertilizers are animal waste. Despite such difficulties, manure is a very popular fertilizer. It is mainly used for horticultural crops. Due to the high nitrogen content, shoot growth and leaf development are accelerated.

Manure belongs to the same class as saltpeter and urea but should not be used together. Otherwise, the balance may be disturbed, which will lead to a loss of yield.

c)       Liquid organic fertilizers

Separating liquid fertilizers into a separate class is not entirely correct. The fact is that they are united by the method of application, and the composition and method of preparation can be very different. Liquid, for example, includes modern complex food preparations, which are synthetic.

In widespread natural farming, liquid infusions are called infusions on conventional organic fertilizers. For example, they are made from manure, compost, and bird droppings. There are popular recipes for making dressings from nettles and weeds. Apply organic fertilizers in liquid form after germination. They improve the soil’s condition but are also absorbed by plants through the leaves.

d)      Fermentation waste

With the development of alternative energy, a digestor is becoming more and more popular. These are solid wastes that are generated during the synthesis of biogas. They contain nitrogen, phosphorus, and potassium, all necessary minerals for plants.

How to fertilize a garden for sowing

1.       Bury in the soil

Spread the down to earth fertilizer reviews on the ground so you can dig up the soil later and leave it buried and mixed. If you use undecomposed fertilizer, do so a few months before planting. 7-10 liters of compost per square meter is sufficient. If it is a strong fertilizer, such as chicken manure, it is recommended to reduce the amount by 1-3 liters per square meter.

2.       Sprinkle on the surface

Sprinkle down to earth fertilizer reviews on the soil’s surface, and nature itself (rainwater) will bring nutrients to the roots. This type of fertilizing, also called mulch, is very effective in forests. This is not recommended for sandy soils, nor is the use of bird-derived fertilizers as they change the pH of the ground and acidify the soil.

How to fertilize a garden for different crops

During spring, it is time to grow eggplants, tomatoes, or peppers in summer. These crops need good fertilizer because they consume a lot of nutrients. Let us know how to fertilize a garden for different crops.

a)      How to fertilize Citrus Fruits

Citrus fruits require a lot of fertilizer, so you should pay attention to this if you want to grow oranges, tangerines, or grapefruits that require the most fertilizer. To know when to fertilize citrus fruits, it is essential to know that when magnesium is deficient, they need to be re-fertilized. 

Therefore, the best time to fertilize citrus fruits is spring and summer. Purchasing a complete citrus fertilizer with an NPK density (18-6-6) will provide the necessary elements and enough citrus to meet the high nutritional requirements of citrus.

If you have a small urban garden or grow fruit trees, the most effective fertilizer is vermicompost. There is no doubt that the best time to fertilize fruit trees is in spring and summer.
