Agricultural Workers Day is celebrated on the second Sunday of October.
New standards on agricultural sector are developed and approved every year.
GOST R 58820-2020 came into force for the first time on July 1. It is applied to phosphogypsum for agriculture, which is used as ameliorant for chemical soil improvement, calcium-sulfur fertiliser, and raw material for compost preparation.
Phosphogypsum is produced as a by-product (waste) in the production of phosphoric acid and phosphate fertilisers from apatite and phosphate rock. It is used in agriculture as well as in construction materials and products.
The new national standard contains a description of phosphogypsum grades (A-1, A-2, B-1, B-2, C-1, C-2), which are classified according to the composition of the raw materials and free (physically and mechanically bound) water. During transportation, phosphogypsum is classified as non-hazardous according to the international classification established by the UN standard rules.
The National Standard contains the description of methods for determination of mass content, metrological characteristics of methods for determination of crystallization water mass fraction in dry matter, methods for determination of cadmium and lead mass fraction as well as arsenic mass fraction, mercury mass fraction in absolutely dry matter.
Phosphogypsum is a non-combustible, fire-explosive substance. When you work with phosphogypsum, you must observe the rules of personal hygiene. You must wash your hands thoroughly with soap and take a shower at the end of the work.
The document includes requirements for environmental protection in phosphogypsum production. In particular, it is not allowed to discharge into water bodies wastewater generated during production without its additional processing at the purification plants.
Guaranteed storage period of phosphogypsum is 6 months from the date of shipment. Shelf life of phosphogypsum is not limited.
Interstate standard GOST 26954-2019, Agricultural mobile machinery. Method for determining maximum normal stress in soil, replaced the eponymous GOST 1986 and came into force on August 1 of this year. The document applies to mobile agricultural machinery - tractors, combines, vehicles, agricultural machinery and other types of machinery that have their own engines used in fields, meadows and pastures.
GOST gives a description of the method for determining the maximum normal voltage arising in the soil in the kilopascals at a depth of h = 0.5 m, for each single propulsor document provides the formulas for calculation.
National standard GOST R 58655-2019, Agricultural mobile machinery. Rates of force produced by propelling agents on soil, came into force for the first time in August 1 of this year.
The document contains norms of maximum pressure of propellers on loamy and clayey soil and normal mechanical stress in soil depending on its humidity in the layer 0-30 cm. Norms are established for agricultural machinery with the largest operating weight of its complete set, determined by the technical documentation and the corresponding type of work performed, and for traction facilities also loaded with nominal traction force.
It contains a table of the lowest water content of soil depending on its mechanical composition: super sandy, light loamy, medium loamy, heavy loamy and clayey. The document also contains an example of calculating the norms of maximum pressure on the soil of the harvesting unit.
