Inexpensive source of sulfur
Since the 1980s, industrial sulphur emissions from the atmosphere and the "acid rain" caused by them have supplied up to 50 kg / ha of sulfur annually.
Currently, this phenomenon has been greatly reduced causing deficiencies of sulphur in the soil.
These deficiencies must be supplemented by mineral fertilisation.
We recommend Sulfagro Ca because:
Improves soil properties
- improves soil structure - less dense soil and no crust guarantees better germination
- provides better water infiltration into the soil preventing erosion
- deeper rooted plants facilitate better absorption of water and nitrogen
- ensures the harvesting of root crops with a small amount of soil
- improves the nutritional value of the crops (more calcium and protein)
- increases resistance to pathogens, improving plant health
Provides Sulphur and Calcium
Benefits of Sulphur intake for an improved crops:
- faster initial growth
- more heads per square meter, more grains per head
- high protein content
- better wintering of rapeseed
- dynamic growth during spring vegetation
- more side shoots and rapeseed flowers
- improved pollination due to the intense colour of the flowers
- higher oil content
- quick nitrogen absorption causes rapid crops growth
- more tyed pods and more seeds in pods
- higher oil content
- better use of solar energy in the early stages of vegetation, as sulphur conditions the absorption of nitrogen from the soil, increases protein synthesis and biomass production
- greater and improved crops
- higher sugar content
- less potatoes diseases: Streptomyces scabies; Rhizoctonia solam
- higher growth rate
- lower nitrate content
- increased nutritional content of vegetables such as carotene, vitamin C, biotin (H) and thiamine (Bi)
- high fibre content
- improved taste and flavouring of bulb vegetables: onions, garlic
- high content of essential oils (cycloalliin - onion and horseradish, allicin - garlic)
The benefits of added calcium to our crops:
- increased nutrients absorption by stimulating root growth
- optimised relationship between nitrogen uptake and other components that determine the efficiency of nitrogen fertiliser
- improved crops health through balanced nutrition and less pathogens
- increased N₂ assimilation due to the development of rhizomes on roots and legumes
Eliminates Al³⁺ toxicity
Decreasing the amount of toxic aluminum ions significantly improves soil fertility. Regular use of Ca amendments is a common way of maintaining the soil functions. In addition, the calcium is also essential to plant growth. It can be stated that as an effect of nutrient uptake and leaching the decrease of calcium reserves can reach up to 200-300 kg CaO / ha.
Sulfagro Ca fertiliser makes the neutralisation of Al³⁺ possible through its two components:
- calcium Ca²⁺
- sulphur in the SO₄²ˉ sulphate form, which binds aluminium in a compound with lower solubility.
Sulfagro Ca slowly dissolves in soil water releasing its two components, Ca²⁺ cation and SO₄²ˉ anion. Calcium removes Al3+ from the soil and then combined with S is converted into aluminium sulphate. The aluminium sulphate acts as a coagulant in the soil improving the soil properties and preventing the hardening of the soil surface. Therefore, toxic aluminium is at least partially excluded from the soil.
Stabilises soil pH
The main side effect of soil acidification is a decreased pH and increase of toxic compounds, mainly aluminium and manganese. These compounds occur in acidic soil (pH below 5.5), and in very acidic soil where its high concentration can damage the crops.
The negative effect of aluminium on crops must be considered in terms of :
- low volume of soil used by the root which causes a lower absorption of N,P,K
- reduced nitrogen efficiency due to phosphorus and potassium deficiency
- decreased activity of microorganisms in the soil
- low rate of decomposed organic matter
- increased risk of vanishing of nitrates and sulfates from soil
- reduction of nitrogen nitrification
- lower activity of symbiotic microorganisms that assimilate N₂
- phosphorus immobilization
- lower calcium and magnesium content in the soil
- activation of toxic compounds, e.g. heavy metals
- increased risk of phosphorus retardation in fertilisers
- slower rate of nitrogen uptake from fertilisers
- increased absorption of unwanted components by plant
- Damage to the soil structure
- less infiltration of rainwater
- increase the risk of soil hardening
- poor root growth in compacted soil
Sulfagro Ca is one of the few sulphur fertilisers that does not acidify the soil and keeps a constant pH level
Streamlines the N₂ action of fertilisers
Sulphur is one of the basic ingredients that determine the crop growth, biomass production and plant reproduction. This element is a component of many enzymes and organic compounds present in the plant. Sulphur deficiency, decreases the absorption of the N₂ which reduces the production of seeds and biomass.
Well-fed crops with Sulfagro Ca fertiliser are more resistant to stressors, in particular:
- biotic - sulphur increases the resistance of crops to infections caused by fungal diseases and bacteria
- abiotic - increasing drought tolerance
The positive effect of fertiliser on the yield is very high for all the crops especially for those prone to sulphur deficiency .
