Regional Calendars, Climate & DataDrought-Year Planting Calendar Adjustments
A dry year does not call for a new calendar so much as a set of adjustments. Moisture, not the date, becomes the deciding factor, and the plan shifts toward protecting what water you have.
Key points
- Check soil moisture below the surface before deciding to plant.
- Follow the final planting dates for your crops and insurance.
- Use mulch, residue and weed control to protect soil moisture.
- Put limited water at the crop stages that matter most.
How do you recognize a drought year early?
Watch several signals together: soil moisture below the surface, the weekly U.S. Drought Monitor map, short- and long-range outlooks from the National Weather Service, and the state of local streams, ponds and wells. One dry week is not a drought, but a dry fall and winter followed by a dry spring is a warning.
Dig a small hole and feel the soil at seed depth and below. If the profile is dry beyond the surface, stored moisture is low, and the crop will depend heavily on rain or irrigation to come. Write down what you find, so that you can compare future years.
Keep a simple rain log with a cheap gauge. Totals since fall, compared with what is normal for your area, give you context that a single week of weather cannot.
- Check the Drought Monitor each week
- Probe soil moisture below the surface
- Note water supply from wells, ditches or ponds
Should you plant earlier, later or on schedule?
There is no single answer, and it depends on the crop and the moisture. Seed needs moisture to germinate, and planting into dry soil may leave seed waiting for rain, with uneven emergence when it comes. In some cases planting into available moisture, even if it means slightly deeper seed placement, gives a better stand.
In others, waiting for a rain is better, as long as you stay within the final planting dates for your crop and insurance. Talk with your extension office or crop adviser about what works for your soils, and check with your insurance agent before changing plans.
How should you change the crop mix?
In a dry year, many growers shift toward crops and varieties that tolerate dry conditions or have shorter water demand, and away from the most thirsty crops. Smaller acreage of high-value irrigated crops, planted well, can beat a larger acreage planted thin.
In gardens, favor crops that handle dry weather, plant fewer thirsty crops and consider containers or beds you can water efficiently. Stagger plantings, so a single heat or dry spell does not hit everything at once. Check your state extension planting guide for the range for your area.
What can you do to conserve soil moisture?
Cover soil with mulch or crop residue, limit tillage that dries the seedbed, and control weeds, which compete for water. Build organic matter over time, since soils with more organic matter generally hold more water. Windbreaks can reduce drying winds.
Plant at the right depth and firm the seed into moist soil so that it contacts moisture. For transplants, water them in and shade them for a few days, so they establish.
Cover crops are a trade-off in a dry year, since they use water too. Ask your extension office or NRCS conservation planner whether to terminate them early, and when, for your soils and the crop that follows.
How do you schedule irrigation when water is limited?
Water by soil moisture and crop stage rather than a fixed calendar. Many crops have stages when water stress hurts the most, such as germination, flowering and fruit or grain fill, and you may choose to put your limited water there. Early morning watering reduces evaporation losses.
Drip irrigation and targeted watering use less water than overhead systems in many settings. Follow local water rules, which vary by community, district and state, and which may tighten in drought. Water rights and delivery schedules are set locally, so confirm them.
Check pumps, filters, hoses and emitters before the dry spell arrives. A leak or clog wastes scarce water, and repairs are easier before the crop needs it. Also learn whether your area has water-use rules that apply to agriculture in drought.
What about insurance, records and support programs?
Crop insurance, disaster assistance and conservation programs are handled through USDA RMA, FSA and NRCS. Ask about reporting deadlines, final planting dates and any special provisions in drought. Keep notes and photos of conditions, planting dates and any problems.
Nothing here replaces advice from your agent or local office, since rules change and vary by crop and county.
Talk with neighbors about shared resources such as equipment and water, since dry years often reward cooperation.
How do you build a drought-year calendar?
For example, if your usual planting window opens in late April and the soil is dry, you might delay a little for rain within the allowed window, plant the most drought-tolerant crops first, hold back a portion of seed or acreage for later and concentrate water on the most valuable crop. This is a worked example of the method, not a date recommendation.
After the year ends, review what you did and what happened, and write down the lessons while they are fresh. Share your notes with your extension office, which uses grower reports to guide future advice.
