Herbicide management is a complex issue since it can cause toxicities to crops and increase soil degradation. I recommend using plastic barriers (mulch) in the soil to control weeds and thus not greatly impact the microflora and microfauna of the soil.

Due to the demand of soybeans regarding bioclimatic aspects such as temperature and photoperiod, any variation of these characteristics is directly linked to morphophysiological changes in the plant during the cycle and consequently in yield.
The adaptability range of each variety changess as it moves north or south on the globe. The closer to the equator, the smaller the amplitude of the photoperiod throughout the year. Therefore, it is important that the sowing of the crop occurs in the correct period and at the latitude adapted to that variety, so that the plant can achieve its maximum production in both the vegetative and reproductive phases. An incompatibility between the variety’s adaptation range with a specific region or weather will result in the reduction of plant size, consequently presenting a smaller number of nodes/pods/grains. In addition, because it is a plant very sensitive to photoperiod, sowing outside the optimal range will cause soybeans to have lower growth potential. For example, when changing the range of a given soybean variety not adapted to high latitudes, its vegetative period will extend greatly, since the ambient photoperiod is longer than the critical photoperiod, causing the plant to spend a lot of energy to produce leaves, directing less energy to the grains. Other problems that can be generated with sowing at the wrong time would be a greater attack of pests, diseases and low water availability, directly impacting grain yield.June 21, 2021 at 9:55 pm #4096Illia VolhaKeymasterHello,
Firstly, the management for any crop establishment begins with planning. The farmer should plan in advance, ensuring that everything is ready for the day of planting. This operation is fundamental to the success of the new crop.
The main objective is to establish a schedule of activities, so that the planting occurs efficiently and safely, for this it must be programmed for soil operations and herbicide applications predicting rainy days, inappropriate days, so that everything occurs efficiently.
Soil analysis should be performed to make the necessary corrections, such as the application of limestone and gypsum, if necessary, the maintenance of machinery, acquisition of healthy seeds and other insums. Managing soil fertility is essential, because once it is accurate, itwill increase the chance of success in the corn crop.
For the maintenance of machines and implements, a frequent check and general adjustment should be made, mainly in the cutting and fertilizer deposition equipments, gears and transmission chains, cutting discs, among others. The planter must be suitable for corn spacing and seed. The seeder must take into account the technological level contained in the seed, resistances, tolerances, to diseases and pests, the soil conditions and climate from which the crop will settle.
Another important aspect for planting is the depth, in which this seed will be deposited in the soil, seeking to be as uniform as possible, to allow an equal emergence, so that the plants do not compete for water, light and nutrients. The fertilizer should be placed about 5cm next to or below the seed. The treatment of seeds with insecticides is recommended because of soil pests, which can impair the initial development of plants. The speed of the tractor is important, not to compromise the planting density.
The delay in planting season usually hinders other operations, especially weed control and pest control. The occurrence of diseases can also happen with these delays.
With regard to fertilization practices, these are extremely important since crop extraction will depend on the yield obtained from the nutrient concentration in grains and straw, so it is necessary to make available to the plant the total amount of nutrients that the plant needs, being supplied by the soil through fertilizationJune 21, 2021 at 9:38 pm #4094Illia VolhaKeymasterHello AnnaG,
The correct time to harvest corn is usually defined by the grain’s physiological maturity. This moment happens together with the total paralysis of dry matter accumulation in the grains, coinciding with the natural process of senescence of the leaves. At this point, the maximum weight and maximum vigor of the seeds are characterized.June 21, 2021 at 9:26 pm #4092Illia VolhaKeymasterHi Anna!
The germination process is triggered by oxygen instilling and absorption, due to differences in osmotic potential between the seed and the environment. The water content needed to raise the water potential of the seed to 1.0Mpa corresponds to 30% to 40% of its mass, being sufficient to trigger the germination mechanism. Being in favorable condition, seedling emergence will occur between 6 to 10 days after sowing.
If you have any other questions, our Smart Fertilizer team will be glad to help!June 21, 2021 at 9:16 pm #4090Illia VolhaKeymasterCrops need a certain degree of nutrition, so it is important to have information on the compounds in the soil, which are obtained in soil analyzes, from there; I could recommend any of our Smart Fertilizer licenses to calculate the most accurate recommendation.
June 21, 2021 at 2:41 pm #4088Illia VolhaKeymasterThe climatic factor is decisive in the production and health of the plants, but the phytosanitary status of the root must be checked, to rule out an attack by some pathogen.
June 21, 2021 at 2:34 pm #4087Illia VolhaKeymasterEstimated;
To carry out a correct fertilization, I recommend carrying out a soil analysis, to observe in what state the land is and to cover nutrient deficiencies, depending on this; could make a recommendation on the fertilizer to use.
June 21, 2021 at 2:24 pm #4086Illia VolhaKeymasterHello, it is very important to take into account the Urea – Water relationship that Salvatore mentioned above to avoid burning in the leaves due to excess nitrogen, it would be important that you use background fertilizations or in the first stages of development of the crop so that you increase the area index foliar and avoid nutrient imbalances in the soil.
