Soil score

Okay

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

Not in the score: manganese.

For most crops. How the soil score works

Rain

About 1,145 mm in Whole year

January–December, in a normal year. A dry year brings about 810 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 (3 nutrients)

  • Nitrogen

    From 44,133 soil tests

    Poor

    Low 98% Medium 2%

    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 44,078 soil tests

    Poor

    Low 93% Medium 6% High 1%

    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 44,252 soil tests

    Poor

    Short 60% Enough 40%

    6 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.

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 44,162 soil tests

    Good

    Low 18% Medium 51% High 31%

    2 in 10 soil tests here came out low

    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 44,191 soil tests

    Good

    Low 19% Medium 68% High 13%

    2 in 10 soil tests here came out low

    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 43,871 soil tests

    Good

    Acidic 1% Neutral 97% Alkaline 1%

    Almost every soil test here came out neutral

    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 43,983 soil tests

    Good

    Not salty 100%

    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 44,199 soil tests

    Okay

    Short 40% Enough 60%

    4 in 10 soil tests here came out short

    If your field is short: use single super phosphate instead of DAP, or add about 100 kg of gypsum per acre before sowing.

    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.

  • Iron

    From 44,277 soil tests

    Okay

    Short 22% Enough 78%

    2 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.

  • Copper

    From 44,189 soil tests

    Good

    Short 1% Enough 99%

    Almost every soil test here had enough

    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.

  • Boron

    From 44,231 soil tests

    Okay

    Short 43% Enough 57%

    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.

The tests here for manganese look like a testing error: almost every test reads the same, unlike the districts around. They aren't used.

Good fit 1

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.

Sowing Growing Harvest

  1. Pineapple

    Holds the land all year

    No figures for your district: its government crop records list no area or yield for this crop. Priced from mandis across your state.

    ₹4.7 lakh–₹7.1 lakh

    per acre a year, before costs

    once bearing, from about year 2

    After typical costs: ₹3.3 lakh–₹5.6 lakh an acre a year

    • Suits: Rain is enough
    • Suits: Ideal temperatures
    • Needs care: Soil 7/10
    Why, and how to make it work

    Water

    Rain is enough in a normal year. Keep one irrigation ready for a dry year.

    Needs about 630 mm of water here in its growing months. Rain gives about 690 mm it can use in a normal year, and 450 mm in a dry year.

    Temperature

    Grows best at 21–30 °C on average, and survives 10–36 °C.

    Here, in its growing months (day / night):

    • Jun 36 °C / 26 °C (outside its best range)
    • Jul 35 °C / 26 °C (outside its best range)
    • Aug 34 °C / 25 °C

    Months in orange are outside its best range.

    Soil

    Soil for Pineapple: 7 out of 10 (okay).

    Not in the score: manganese.

    • The pH here suits it.
    • Many fields here are short of zinc, which it needs a lot.
    • Many fields here are short of boron, which it needs a lot.
    • Most fields here are short of nitrogen.

    Likes pH 4.5–6.5.

    How the soil score works

    Money

    Yield: about 124 quintals an acre, the typical figure in your state (its government crop records list none for your district).

    A new planting gives its first real harvest after about 2 years. The money here is for plants already bearing.

    Mandi price at last season's harvest (September 2026): about ₹4,750 a quintal across mandis in your state.

    Prices are usually best in April.

    Typical costs are about ₹1.4 lakh an acre: about half of what a usual harvest earns (2023–2025), as in farm cost surveys. They are spent whatever the harvest.

    How to make it work

    • Short of nitrogen Your soil is likely short of nitrogen.

      Add about a quarter more urea than the usual dose, in two or three splits. A pulse crop in rotation also adds nitrogen.

      Ask your Krishi Vigyan Kendra what to add for this crop.

    • Short of organic carbon Your soil is likely short of organic carbon.

      Add 4 tonnes of compost or farmyard manure per acre before sowing, and plough crop leftovers back in instead of burning them.

      Ask your Krishi Vigyan Kendra what to add for this crop.

    • Short of zinc Your soil is likely short of zinc.

      Mix 10 kg of zinc sulphate per acre into the soil before sowing. One dose lasts two or three seasons.

      Ask your Krishi Vigyan Kendra what to add for this crop.

Possible, with effort 3

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

Sowing Growing Harvest

  1. Tapioca (Cassava)

    Holds the land all year

    Grown on 7,696 acres here. Priced from mandis across your state.

    Only with irrigation: rain gives too little of its water to count on

    • Needs care: Risky: 8 irrigations short
    • Suits: Ideal temperatures
    • Needs care: Soil 7/10
    Why, and how to make it work

    Water

    Rain falls about 8 irrigations (5 cm each) short in a normal year, so it's risky without water.

    Needs about 1,050 mm of water here in its growing months. Rain gives about 690 mm it can use in a normal year, and 450 mm in a dry year.

    Temperature

    Grows best at 20–29 °C on average, and survives 10–35 °C.

    Likes pH 5.5–8.0.

    How the soil score works

    Money

    Yield: about 178 quintals an acre here in this season (district figures).

    Rain gives it too little of the water it needs, so there's no income figure on rain alone: grow it only with irrigation.

    Mandi price through the year (December 2025–November 2026): about ₹3,125 a quintal across mandis in your state.

    This week: about ₹3,750 a quintal, the middle of 7 mandis in your state (latest 13 Nov).

    Prices are usually best in September.

    Typical costs are about ₹2.4 lakh an acre: about half of what a usual harvest earns (2023–2025), as in farm cost surveys. They are spent whatever the harvest.

    How to make it work

    The better districts with similar soil, rain and warmth get 151 quintals an acre. That's a realistic target.

    • Short of nitrogen Your soil is likely short of nitrogen.

      Add about a quarter more urea than the usual dose, in two or three splits. A pulse crop in rotation also adds nitrogen.

      About 100% of local fields of this crop get it.

    • Short of organic carbon Your soil is likely short of organic carbon.

      Add 4 tonnes of compost or farmyard manure per acre before sowing, and plough crop leftovers back in instead of burning them.

      Few local farmers add it to this crop, so it's an easy place to get ahead.

    • Short of zinc Your soil is likely short of zinc.

      Mix 10 kg of zinc sulphate per acre into the soil before sowing. One dose lasts two or three seasons.

      Few local farmers add it to this crop, so it's an easy place to get ahead.

    What local farmers put on it (share of fields):

    • Muriate of Potash (MOP) 100%
    • Urea 100%
    • NPK Mixture 89%
    • Di-Ammonium Phosphate (DAP) 75%
