Sulfur (S) – Sulfur

Plants absorb sulfur in the form of sulfur ion (SO₄^2-)

1. Effects of sulfur on plants:

* Sulfur in arable land:

The amount of sulfur lost after each growing season ranges from 10 to 50 kg / ha. Except for some cereal crops, the amount of sulfur lost is usually equivalent to the amount of P lost after each harvest.

The amount of sulfur needed to replenish is usually two to four times the amount lost. Important sources of sulfur are the atmosphere, water, fertilizer, pesticides, fungicides.

* Sulfur for crops:

Applying sulfur not only increases crop yields but also:

– Increased protein intake, especially for food crops

– Reduce N: S ratio, which will reduce the nitrate content of farm produce.

– Provide more flavor for food, food.

– increase the photocatalytic function

– Create the characteristic taste of each crop.

– Increasing drought tolerance, resistance to pests and diseases

The total amount of sulfur needed depends on the type of plant and the productivity of the agricultural product. Protein-rich plants have higher sulfur needs. Oil crops need more sulfur than cereal.

Maize gives the highest productivity when fertilizing 90 kg / ha of sulfur

For rice is 25 kg/ha.

Sugarcane increased by 42 kg/ha of sulfur yield increased 53 – 77 tons/ha, sugar content increased from 8.5 to 8.9%.

Peanuts are plastered to increase protein content by 8.4%, 21% methionine and 12% oil content.

Sulfur application also has an indirect effect on the livestock industry as grassland is supplemented with sulfur, which results in a higher yield of green matter, a markedly increased protein content, and a reduction in harmful nitrate levels.

* Expression of sulfur deficiency in plants:

                                          Expression of sulfur deficiency on peach leaves and tomatoes

Lack of sulfur, young leaves turn yellow light, stunted, under developed, growth of the flower is limited, the number of flowers decreased.

When deficient, the symptoms manifested as lack of protein; Small leaves, evenly golden, fall off early. Growth of the shoots is limited, affecting the number of flowers, stems, small and early wood.

Some photos of plants are lacking in sulfur:

                                                                             Lack of sulfur in bonsai

                                           Plants are deficient in sulfur, yellow leaf, small leaf, stunted stunted growth

                                                                            Corn leaves are deficient in sulfur

2. Some fertilizer products provide sulfur for soil and crops
