Soil score

Okay

Short in most fields here: nitrogen, organic carbon, zinc and iron.

For most crops. How the soil score works

Rain

About 692 mm in Whole year

January–December, in a normal year. A dry year brings about 501 mm.

Temperature

Days about 34 °C, nights 24 °C in Whole year

Typical of the district's villages; a farm much higher or lower can be a few degrees cooler or warmer.

What's short in your soil, and what to do (4 nutrients)

  • Nitrogen

    From 9,598 soil tests

    Poor

    Low 100%

    Almost every soil test here came out low

    If your field is low: add about a quarter more urea than the usual dose, in two or three splits. A pulse crop in rotation also adds nitrogen.

    What this means

    Grows leaves and stems. Short soil gives pale, yellow leaves.

    Low under 280 kg/ha Medium 280–560 kg/ha High over 560 kg/ha

    Healthy soil has 280 kg/ha or more.

  • Organic carbon

    From 9,595 soil tests

    Poor

    Low 90% Medium 10%

    9 in 10 soil tests here came out low

    If your field is low: add 4 tonnes of compost or farmyard manure per acre before sowing, and plough crop leftovers back in instead of burning them.

    What this means

    Shows how much organic matter the soil has. It keeps soil loose, holds water and feeds the crop slowly.

    Low under 0.5% Medium 0.5–0.75% High over 0.75%

    Healthy soil has 0.5% or more.

  • Zinc

    From 9,590 soil tests

    Poor

    Short 75% Enough 25%

    7 in 10 soil tests here came out short

    If your field is short: mix 10 kg of zinc sulphate per acre into the soil before sowing. One dose lasts two or three seasons.

    What this means

    Needed for growth and healthy leaves. Rice and wheat often run short.

    Short under 0.6 ppm Enough 0.6 ppm or more

    Healthy soil has 0.6 ppm or more.

  • Iron

    From 9,596 soil tests

    Poor

    Short 76% Enough 24%

    8 in 10 soil tests here came out short

    If your field is short: spray ferrous sulphate, 5 g per litre of water, when young leaves turn yellow.

    What this means

    Keeps young leaves green.

    Short under 4.5 ppm Enough 4.5 ppm or more

    Healthy soil has 4.5 ppm or more.

Fixes are the usual advice. Your Soil Health Card or nearest Krishi Vigyan Kendra gives the exact dose for your field.

Other soil results

  • Phosphorus

    From 9,598 soil tests

    Okay

    Low 31% Medium 38% High 31%

    3 in 10 soil tests here came out low

    If your field is low: add about a quarter more DAP or single super phosphate than the usual dose, at sowing.

    What this means

    Builds roots and helps the crop flower and fill grain.

    Low under 10 kg/ha Medium 10–25 kg/ha High over 25 kg/ha

    Healthy soil has 10 kg/ha or more.

  • Potassium

    From 9,598 soil tests

    Good

    Low 5% Medium 37% High 58%

    Most soil tests here came out high

    If your field is high: you can use about a quarter less potash than usual.

    What this means

    Fills grain and fruit, and helps crops stand drought and disease.

    Low under 110 kg/ha Medium 110–280 kg/ha High over 280 kg/ha

    Healthy soil has 110 kg/ha or more.

  • pH

    From 9,592 soil tests

    Good

    Acidic 3% Neutral 89% Alkaline 8%

    1 in 10 soil tests here came out alkaline

    What this means

    How sour (acidic) or alkaline the soil is. It decides which nutrients roots can take up.

    Acidic Neutral Alkaline

    In these tests, neutral means about pH 6 to 8, which suits most crops; acidic is below about 6 and alkaline above about 8.

  • Salt

    From 9,593 soil tests

    Good

    Not salty 99% Salty 1%

    Almost no soil tests here came out salty

    What this means

    Salt in the soil, shown as EC on the card. Salt makes it hard for roots to drink.

    Not salty Salty

    Under 1 dS/m is fine. Between 1 and 4, only crops that can't take salt lose yield. Above 4 harms most crops.

  • Sulphur

    From 9,598 soil tests

    Good

    Short 16% Enough 84%

    2 in 10 soil tests here came out short

    What this means

    Makes oil in oilseeds and protein in pulses.

    Short under 10 ppm Enough 10 ppm or more

    Healthy soil has 10 ppm or more.

  • Copper

    From 9,556 soil tests

    Good

    Short 7% Enough 93%

    1 in 10 soil tests here came out short

    What this means

    Helps the crop set seed and resist disease.

    Short under 0.2 ppm Enough 0.2 ppm or more

    Healthy soil has 0.2 ppm or more.

  • Manganese

    From 9,598 soil tests

    Okay

    Short 26% Enough 74%

    3 in 10 soil tests here came out short

    If your field is short: spray manganese sulphate, 5 g per litre of water, on the young crop.

    What this means

    Helps leaves make food from sunlight.

    Short under 2 ppm Enough 2 ppm or more

    Healthy soil has 2 ppm or more.

  • Boron

    From 9,588 soil tests

    Okay

    Short 35% Enough 65%

    4 in 10 soil tests here came out short

    If your field is short: mix 4 kg of borax per acre into the soil before sowing.

    What this means

    Needed for flowers to set seed and fruit.

    Short under 0.5 ppm Enough 0.5 ppm or more

    Healthy soil has 0.5 ppm or more.

Good fit 0

Water, temperature and soil type suit; amber shows what needs care, such as nutrients to add. Sorted by what is likely left per acre after costs; risky crops come lower.

Nothing fits well this season. Look at the crops below that are possible with effort, or try another season.

Possible, with effort 0

Each needs something extra: irrigation, soil care or a careful sowing time, or it likely loses money at typical costs. The card says what.

No crops in this group.
