What is rapeseed? What are the benefits of rapeseed cultivation?
The important features of canola include a high oil content in its seeds, its fall growth cycle (in comparison to summer oilseed plants such as sunflower and soybeans), and its ability to thrive in various climatic conditions. Cultivation of this plant is carried out in many regions around the world due to its agricultural, economic, and environmental advantages.

What are the features and advantages of conservation tillage method?
Conservation tillage practices offer many benefits to farmers by avoiding tillage operations, preserving crop residues, and using residual ridges as seedbeds. These methods reduce surface evaporation and soil surface heat on hot days, and also help to improve soil permeability and water retention capacity by maintaining more soil moisture and increasing its organic matter. Reducing the use of chemical fertilizers and herbicides, as well as reducing soil permeability and water consumption, are other advantages of these methods. Higher working speed and reduction of seed consumption increase the efficiency and productivity of the farm. Financial and energy productivity are also among the economic benefits of these methods. With implementation possibilities in special conditions such as high soil moisture or excessive dryness, these methods provide a sustainable and efficient agricultural model.

What is conservation tillage? Measures to preserve soil and moisture
Considering the low rainfall conditions in our country and the importance of maintaining soil moisture, conservation tillage is very important, especially during periods of drought. It is necessary to choose tillage methods that preserve the maximum amount of plant residues on the soil surface in order to preserve soil moisture and protect our country's environment from the unfavorable effects of climatic conditions.

What is sugarcane? How is sugarcane cultivated?
Sugarcane is an important sugar plant with a long history of cultivation. It is rich in sugar and is used in the production of both white and brown sugar. Sugarcane juice, abundant in essential nutrients, is highly nutritious and healthy. The stalk of sugarcane, containing 14 to 17 percent sucrose, is utilized in the manufacturing of paper, cardboard, as well as, after sugar extraction, its by-products such as molasses and bagasse are used in the production of alcohol and animal feed, respectively. Sugarcane is a monocot plant, meaning it does not undergo crop rotation and is cultivated independently. After a harvesting period of approximately 5 to 6 years, it undergoes a resting period before being cultivated again. In India, sugarcane and rice are commonly cultivated side by side.

What is the importance of soil organic matter in corn cultivation?
Organic matter in the soil plays an essential role in fertility, water holding capacity and overall strength of the soil. It is estimated that approximately 50% of soil organic matter in most soils was lost in the first 100 years after grasslands and savannahs were converted to agricultural land. Reducing soil erosion through methods such as conservation tillage is very important in soil conservation, saving billions of tons of topsoil, especially on vulnerable lands.

The importance of organic matter in agriculture and adding fertilizer to agricultural soil
According to the definition, any substance that has carbon in its molecules and originates from a living organism is called an organic substance. Organic materials act as materials that connect soil particles and the structure of soil grains, and the more it is, the better.

How to take samples of agricultural soil
Before sampling, we clean the surface of the sampling site from pebbles, weeds and any impurities. The sampling depth depends on the type and age of the plant. The appropriate depth for most crops is 0 to 10 cm, but sometimes for some plants with deep roots (such as alfalfa), samples are taken from a depth of 30 to 60 cm.

Time and conditions of agricultural soil sampling
The best time to take samples from fields is one month before planting or one month after harvesting. Because during these times, the soil conditions are more stable and the obtained results are more reliable. Also, controlling and improving the soil is much easier and costs less.
