ABSTRACT 

One of the most convenient ways to increase soil fertility is siderate crops. They enrich the soil with organic matter, 

increase the activity of microorganisms in the soil and enrich the soil with necessary nutrients due to biomass.

INTRODUCTION

There are many ways to increase soil fertility, and 

siderate crops are considered the best. Green manures 

are planted in order to enrich the soil with organic 

matter and nitrogen. This type of crops is an 

economically useful and ecologically safe source of soil 

enrichment with organic fertilizers. They 

fundamentally improve the properties of the soil, the 

activity of microorganisms in the soil, prevent erosion 

and salinity, and increase the quality of the product. 

The effectiveness of planting siderate crops is close to 

the effectiveness of manure. The green mass of this 

type of crops is rich in nitrogen, protein, starch, sugar 

and various microelements. Unique nodular bacteria 

are formed in the roots of any plant, they absorb free 

nitrogen from the air and play an important role in 

increasing soil fertility. But if the siderates remain on 

the ground for a long time without being harvested in 

time, its coarse stem becomes a source of viral and 

fungal diseases without rotting well under the soil. 

When the ground covered by the siderate plant is 

turned over, the green mass can oversaturate the soil 

with nitrogen. As a result, the next crop cannot digest 

it and begins to burn. For this reason, you should not 

wait until siderat crops begin to ripen. In order to avoid

such a situation, it is necessary to determine the 

expected yield before planting siderate crops. Also, 

before planting, it is necessary to study the 

agrotechnical characteristics of siderat crops well. 

These types of plants include rapeseed, oats, triticale, 

rye and others. 

According to E.V.Shatskikh, D.M.Galiev, 

I.V.Rogozinnikova, A.N.Masliuk [7], the inclusion of 

perennial legumes in the crop rotation system has a 

positive effect on the biological activity in the soil. The 

number of microorganisms in the soil increases, the 

decomposition of plant residues improves, soil fertility 

increases. 

V.S.Polous, S.P.Stepanov, L.O.Prokopova, 

S.N.Osaulenko [13] analyzed the work carried out on 

the use of organic mineral fertilizers, microorganisms 

and resource-saving technologies to stabilize the 

biological activity of the soil. 

As a result of cultivation and irrigation, the irrigated 

gray-meadow soils of the Mirzachol oasis have gone 

through various evolutionary stages and have their 

own properties and characteristics [5,6,8-11]. 

Increasing the soil fertility in saline areas, using it as a 

drain will lead to a decrease in the level of seepage 

water in cultivated areas, and an improvement in soil 

reclamation [1,2,3,4,12]. 

One of the main activities in increasing soil fertility by 

improving soil properties is the use of intercrops as 

siderates. The application of green manures enriches 

the soil with organic matter, improves its general 

physical properties and enhances microbiological 

processes, and leads to an increase in the amount of 

nitrogen and mobile phosphorus in the plowed layer of 

the soil. Green manures have a positive effect on the 

state of the soil aggregate, volume mass, water 

permeability, soil moisture and temperature, the 

amount of nutrients and many other properties.

Siderate crops increase soil biomass, as a result, soil 

fertility increases, microbiological processes 

accelerate, and the amount of humus increases. The 

average biomass in the areas planted with siderate 

crops (2023-2024) was 15.1-16.9 t/ha. In the

experimental field, the highest biomass was observed 

in the rapeseed plant, 16.9 t/ha (table 1). 

Planting siderate crops is one of the best ways to 

improve soil fertility, but it is not widely used. Green 

manures are important in enriching the soil with 

organic matter and thereby improving the physical 

properties of the soil. In the experimental options, 

when studying the condition of soil volume weight 

before planting and after siderates, we observed that 

the volume weight of the soil of the experimental area 

is equal to 1.36-1.41 g/cm3 on average, and after 

planting siderates, the soil volume weight changed to 

1.26-1.33 g/cm3 possible Among the experimental 

variants, the best volume weight difference change 

can be seen in the radish plant variant of 0.11% (table 2).

Siderate crops also affect the physical and physical-

mechanical properties of the soil. The physical 

properties of the soil are improved, the porosity of the 

soil increases, as a result, the volume mass of the soil 

decreases.In the experiment, we can see that the soil 

porosity in the 0-30 cm layer of siderate planted areas 

before planting was 49.26-51.41%, and after planting 

siderate crops, we can see that the porosity in the 

fields of experimental options increased to 52.36-

54.67%. (table 3).

experimental options have a positive effect on several 

properties of the soil. In this case, we can see that the 

highest biomass of the soil is accumulated in the 

rapeseed plant, on average 16.9 t/ha, and the physical 

properties of the soil are improved, having a positive 

effect on the soil volume weight and soil porosity. The 

best index of soil density was observed in radish plant, 

which was 1.37 g/cm3 in khaydov layer before planting, 

and 1.26 g/cm3 after siderates. The difference in the 

change of soil porosity under the effect of siderates is 

around 2.15-4.07%, and the best porosity is 3.99-4.07% 

observed in siderate of radish plant. In general, the use 

of siderate crops as green manure improves the 

general physical properties of the soil, reduces soil 

salinity, their roots serve as drainage, reduces the 

amount of tillage, weeds, diseases and insects, softens 

the soil, prevents erosion and improves soil fertility 

with other positive properties increases.
