Agriculture · farms, greenhouses, poultry

Farms, greenhouses and poultry units in Oman buy chemicals for three jobs: feeding crops through fertigation, correcting micronutrient deficiencies in alkaline soils, and keeping animal housing clean and feed in good condition. Oman Chemical supplies sulphate salts, nitrates, urea, humic acid, feed additives and farm disinfectants from Barka, in the Batinah farming belt.

Farm problems and the chemicals that solve them

Most soils in Oman are calcareous with a high pH, and well water used for irrigation is often saline. At high pH, iron, zinc and manganese become less available to plants, which is why micronutrients are widely applied, and salinity makes careful fertigation more important.

  1. Fertigation

    Drip-irrigated crops are fed through the irrigation water, so fertilisers must be fully soluble and compatible in the stock tanks.

    Chemical typesUrea, calcium nitrate, potassium sulphate, magnesium sulphate and phosphoric acid. Keep calcium nitrate in a separate stock tank from sulphates and phosphates.

  2. Micronutrient deficiencies

    High-pH soils lock up iron, zinc and manganese, showing as yellowing between the veins of the leaves.

    Chemical typesIron sulphate, zinc sulphate, manganese sulphate, copper sulphate and boron, applied to soil, through drip lines or as foliar sprays.

  3. Drip line maintenance

    Carbonate scale and bacterial slime block drippers and cause uneven watering.

    Chemical typesAcid flushing with phosphoric or nitric acid to dissolve carbonate scale; chlorination with hypochlorite to clear slime.

  4. Soil condition

    Saline and sodic soils lose structure and drain poorly.

    Chemical typesHumic substances as soil conditioners; calcium sources such as gypsum where sodium is the problem.

  5. Poultry and livestock

    Feed must be balanced and protected from mould, and houses must be cleaned and disinfected between flocks.

    Chemical typesFeed additives such as dicalcium phosphate and propionic acid; poultry house disinfectants and slaughterhouse cleaners.

Farm chemicals: questions buyers ask

Which fertilisers can be mixed in one stock tank?

Keep calcium nitrate in one tank and sulphates and phosphates, such as magnesium sulphate, potassium sulphate and phosphoric acid, in another. Calcium mixed with sulphate or phosphate at stock concentration forms insoluble gypsum or calcium phosphate that blocks filters and drippers.

Why do my plants have yellow leaves with green veins?

This is interveinal chlorosis. On young leaves it usually points to iron or manganese deficiency, which is common on high-pH soils; on older leaves it often points to magnesium. A leaf or soil test confirms the cause before you treat.

How are blocked drippers cleaned?

By injecting acid, such as phosphoric or nitric acid, to dissolve carbonate scale, and chlorine to clear bacterial slime, then flushing the laterals. Do not inject acid and chlorine at the same time.

What is magnesium sulphate used for on farms?

It supplies magnesium and sulphur, which crops need for chlorophyll and protein. It dissolves easily, so it is used in fertigation and foliar sprays.

Do you supply poultry farm disinfectants and feed additives?

Yes. We supply poultry house disinfectants, slaughterhouse cleaners and feed additives such as dicalcium phosphate and propionic acid. Send your list for a quote.
