Weather is not just something to “check”; it is a decision-making tool for the farm. In India, IMD’s agromet advisory system gives district/block-level forecasts for rainfall, maximum and minimum temperature, wind speed and direction, relative humidity, and cloudiness, and these advisories are issued twice a week to help farmers plan day-to-day operations.
1) Start with the crop stage, not just the forecast
The most useful weather advice is always crop-specific. IMD’s SOP says advisories are built around the crop, the district or block, normal sowing dates, soil moisture, crop stage, and even crop-pest relationships. That means the same rain forecast can mean very different things for a seedbed, a flowering crop, or a crop ready for harvest.
2) Read rainfall first
Rainfall is usually the first thing to check because it affects sowing, irrigation, harvesting, and other field operations. IMD forecasts and agromet bulletins are designed to help farmers take those kinds of decisions, and extension work on weather advisories says accurate forecasts help with planning sowing, irrigation, and harvesting, while extended-range forecasts help farmers prepare for dry spells or heavy rain.
A practical rule is simple: if heavy rain is likely soon, avoid jobs that need a dry field or dry leaf surface. That is an inference from the forecast variables IMD provides, especially rainfall, cloudiness, and humidity.
3) Check maximum and minimum temperature
Maximum temperature tells you how hard the crop may be pushed by heat during the day, while minimum temperature helps you judge night stress, fog risk, and slower crop recovery. FAO notes that changes in temperature and precipitation affect soil moisture, crop yields, and production risk, and that high temperatures can push crops close to their tolerance limits.
In practice, a hot forecast means you should think about irrigation timing, mulch, shade for seedlings, and whether a transplant or spray should wait for a cooler window. That is especially important in vegetables, young transplants, and container plants.
4) Use wind, humidity, and cloudiness to judge timing
Wind speed and direction matter because IMD includes them in district/block forecasts for agriculture. High wind can make spraying less effective and more likely to drift, while higher humidity and cloudiness often mean slower drying after irrigation or spraying. IMD’s advisory system also includes pest and disease risk advisories, which is useful because wetter, cloudier conditions can raise disease pressure in many crops.
That means a forecast is not just “rain or no rain.” It is a way to judge whether the day is good for spraying, fertilizing, transplanting, or leaving the field alone. That is an inference from the weather variables IMD says it uses in agromet bulletins.
5) Use short-range forecasts for operations and longer-range forecasts for strategy
IMD’s agriculture forecasts go up to five days at district/block level, and they are refreshed twice a week. Those are the forecasts you should use for immediate field work. For bigger decisions, like changing sowing dates, selecting short-duration varieties, or preparing for a dry spell, extended-range forecasts are more useful because they help you anticipate larger weather patterns rather than just tomorrow’s weather.
FAO also emphasizes that adaptation in agriculture is not just about surviving one weather event; it is about adjusting crops, varieties, and management to a changing pattern of temperature, rainfall, and extremes.
6) A simple daily weather routine for farmers
A practical routine is easy:
Check the forecast in the morning, match it with the crop stage, then decide what to do that day. If rain is likely, shift sowing or spraying. If it is very hot, protect the root zone and reduce stress. If wind is high, avoid spray work. If humidity is high and clouds are building, watch for disease risk and slow drying. This is exactly the kind of day-to-day planning IMD’s agromet advisory system is built to support.
7) How Biosar fits into weather-based planning
This is where Biosar fits naturally. Biosar’s site shows a range that includes biofertilizers, organic fertilizers, bio stimulant-type products, micronutrients, soil conditioners, and related nutrient-management inputs. When you plan around weather, it becomes easier to choose the right input at the right time instead of applying everything blindly.
That matters because weather-based farm planning is really about timing: using the forecast to decide when to feed, when to protect, and when to wait. For growers, that usually means less waste, fewer mistakes, and better crop response. Biosar’s microbial and soil-health products can fit into that logic because they are most useful when they are timed to crop need, soil condition, and the weather window ahead.
The simplest way to remember it
-
-
- Read weather in this order:
- Rain first
- Then temperature
- Then wind
- Then humidity Then crop stage
-
If you do that consistently, your farm work becomes more planned and less reactive. That is the real value of agromet advisories.
