- Soil Testing Calendar: When to Sample
A soil test is only useful if the results reach you before you make buying and spreading decisions. The best sampling date is the one that fits your... - Lime Application Timing Calendar
Lime works slowly, so timing it well means thinking months ahead of planting. The goal is to give the material time to react with the soil before... - Fertilizer Timing for Vegetables
Vegetables take up nutrients at different rates over the season, so when you feed matters almost as much as what you feed. A simple plan splits... - Fertilizer Timing for Field Crops
Field crop fertilizer timing is a balance between convenience and loss risk. Nutrients applied too early may be lost before the crop uses them, while... - Side-Dressing Calendar for Row Crops
Side-dressing puts nitrogen on after the crop is up, closer to when it takes the nutrient in. A good side-dress plan is built around crop stage,... - Foliar Feeding Calendar
Foliar feeding sprays dilute nutrients on leaves instead of putting them in the soil. Research from several universities shows it is a supplement for... - Compost Application Calendar
Compost builds soil structure and feeds soil life, but it also carries nutrients you should count. The best time to apply it depends on what the... - Manure Application Timing by Crop
Manure is a valuable nutrient source, but timing decides whether those nutrients feed the crop or move into streams. Match the application to the... - Cover Crop and Soil Moisture Calendar
Cover crops use water while they grow, and they leave residue that can hold moisture afterward. Termination timing is the main way to balance those... - Irrigation Scheduling by Crop Stage
A crop needs different amounts of water at different stages, so a flat weekly schedule wastes water early and may leave the crop short at critical... - Drip Irrigation Calendar
Drip irrigation delivers water slowly to the root zone, which saves water and keeps foliage dry. A calendar for drip is less about watering dates and... - Sprinkler Irrigation Timing
Sprinklers lose more water to evaporation and wind than drip systems, so when you run them matters. Timing choices can cut waste and reduce disease... - Watering Calendar for Raised Beds
Raised beds drain faster and warm sooner than ground-level gardens, so they usually need more attention to water. A seasonal approach helps you... - Watering Calendar for Containers
Containers hold little soil, so they swing from wet to dry faster than any other kind of planting. Good container watering is about frequent checks... - Drought Response Calendar
Drought rarely arrives all at once, so a response plan works best when it is organized by stage. Preparing before the dry spell, acting as it builds... - Soil Temperature and Planting Timing
Seeds respond to the temperature of the soil around them, not to the date on the calendar. Measuring soil temperature properly keeps you from... - Soil Moisture Monitoring Calendar
Checking soil moisture on a regular schedule turns watering from a guess into a decision. The tools range from a trowel to buried sensors, and the... - Mulching Calendar by Season
Mulch does different jobs in different seasons: warming in spring, cooling and moisture saving in summer, protection in winter. Timing and material... - No-Till Soil Management Calendar
No-till replaces tillage with careful timing: of residue, of cover crops and of planting. A calendar helps because every season sets up the next. - Tillage Timing Calendar
Tillage at the wrong moment can leave compaction and cloddy ground that last for years. Choosing the right day depends on soil moisture more than the... - Soil Health Calendar for Vegetable Gardens
Healthy garden soil crumbles, drains, holds water and supports steady growth. Building it is a matter of small habits spread across the year, not one... - Soil Health Calendar for Field Crops
Soil health on a farm is built by a series of decisions made through the year, from residue at harvest to traffic at planting. A calendar lets you... - Compaction Prevention Calendar
Compaction is much easier to prevent than to fix. Most of it comes from driving on soil that is too wet, so timing and traffic decisions do the most... - Erosion Control Timing Calendar
Soil loss happens in short, intense events, so erosion control is about having protection in place before the storm arrives. Timing the cover, the... - Nutrient Management Planning Calendar
A nutrient management plan is easier to keep when it follows the year. Tests, decisions, applications and records each have a natural season. - Nitrogen Timing for Corn
Corn takes up most of its nitrogen in a short stretch after the plant is well established, so the goal of timing is to have nitrogen in the root zone... - Phosphorus and Potassium Application Timing
Phosphorus and potassium behave very differently from nitrogen, which gives you more flexibility on timing but also a few specific traps worth... - Micronutrient Application Calendar
Micronutrients are needed in tiny amounts, and the most common mistake is applying them on a calendar instead of on evidence that the crop or soil... - pH Management Calendar
Soil pH changes slowly, so the best pH plan starts months before the crop needs it and repeats on a steady testing schedule. - Salinity Management Calendar
Salt problems build slowly and show up as slow germination, stunting and wilting in fields that seem to have enough water, so a calendar of testing... - Irrigation System Maintenance Calendar
A few hours of checking before the season and a monthly walk-through during it save water, protect yields and prevent the freeze damage that destroys... - Rainwater Harvesting Calendar
Collecting rain works best when the barrel is set up before the rains you want to catch and drained before the freeze that would split it. - Greywater Irrigation Calendar
Greywater can stretch a water supply, but it comes with legal, health and soil questions that need answers before the first drop reaches a bed. - Soil Solarization Timing
Solarization uses sun-heated soil under clear plastic to reduce weeds and some soil pests, and it only works if you run it during the sunniest,... - Biofumigation Calendar
Biofumigation uses certain cover crops, mostly in the mustard family, that release natural compounds when chopped and worked into moist soil, and the... - Cover Crop Termination and Planting Calendar
The best cover crop plan works backward from the day you want to plant the next crop, because termination date decides how much water, nitrogen and... - Green Manure Timing Calendar
A green manure is grown to be worked back into the soil, and its value depends on cutting it while it is still tender and giving the residue time to... - Crop Residue Management Calendar
What you do with stalks and stubble in the weeks after harvest affects erosion, spring soil warm-up, disease carryover and how smoothly the next crop... - Soil Amendment Timing Calendar
Soil amendments differ widely in how fast they act, so the right time to apply each one depends on what it does and how long it takes to do it. - Organic Matter Building Calendar
Soil organic matter builds slowly and is lost quickly, so the useful way to think about it is as a steady yearly routine and not a one-time fix. - Soil Testing After Harvest
The period right after harvest is a convenient time to sample soil, because fields are open, labs are less rushed and you have months to act on the... - Fall Soil Preparation Calendar
Fall work is about doing the jobs that take time or that spring weather will not allow, and then protecting the soil through winter. - Spring Soil Preparation Calendar
Spring soil preparation is mostly about patience, since working ground that is too wet does more harm than starting a week late. - Bed Preparation Timing Calendar
Good beds are prepared in stages, with the slow jobs done well ahead and the finishing touches left until just before planting. - Potting Soil and Seed Starting Mix Calendar
The mix you start seeds in and the mix you pot them up into are different jobs, and both need to be ready before the seed trays come out. - Compost Turning Calendar
A turning schedule is a starting point, and the pile itself, through its heat, moisture and smell, tells you when it actually needs attention. - Vermicompost Harvest Calendar
Harvesting vermicompost is a matter of reading the bin, because the right time depends on how fast the worms have worked, not on a set date. - Manure Composting Calendar
Composting manure takes months, and the calendar has to account for building the pile, the active phase, curing and a safe window to spread it. - Soil Moisture Before Planting Checklist
Seeds need steady moisture at planting depth, and checking it takes a few minutes with a trowel and your hands before you commit to a planting date. - Annual Soil Fertility Calendar Template
A fertility calendar works best as a repeating cycle of testing, planning, applying and recording that you adjust to your own crops and climate.
