Jambo, farmers. Seed, fertiliser and field work are already paid for when your maize begins to emerge. The next task is to check whether that investment has established an even crop. Give each block its own first-month record, and use what you learn to improve preparation on the blocks you have not planted yet. Count days from your actual sowing date in Narok, Nakuru or your own location.
Use a practical maize establishment checklist to track emergence, roots, soil conditions and costs, then prepare your next planting block with better records.
Buy HumiBakt for 1 acre →Start with a planting-day handover
Record the block name, measured acreage, sowing date, variety, seed lot, spacing and the operations completed. Add fertiliser placement, soil preparation, HumiBakt application if used, water conditions and the responsible operator.
A 200-acre farm needs records for each block. If sowing takes several days, label those dates separately so the team compares plants of similar age. Mark observation points and the treated and comparison areas before the first visit.
Count plants and map the gaps
After emergence begins, count plants along several fixed, measured row lengths in representative parts of each area. Repeat the counts at the same points and write down the dates. Ask your local agronomist to interpret the stand against the variety, spacing and field conditions.
Map patches with missing or delayed plants. Check the sowing record, seed placement, crusting and moisture before deciding on corrective work. Agree any replanting decision with crop-appropriate advice; a universal day or threshold will not fit every maize field.
Inspect the root zone alongside the crop
At comparable points, inspect moisture below the surface, crusting, ponding and visible restriction. Lift a small, consistent sample of plants carefully, retaining enough soil to see the root system. Photograph roots with a ruler and label the block and date.
Record root depth and branching as observations. A single root photograph cannot establish a yield response or explain every cause. Soil assessment combines several indicators and compares patterns across time or locations.
Turn observations into named actions
Keep a short action list: what needs checking, who will do it and when the block will be revisited. Have a qualified adviser review unexplained weak patches or unusual symptoms. Record the observation first and the confirmed explanation separately.
Follow the maize nutrient, weed and water programme agreed for the field. HumiBakt fits into a broader soil-management programme; keep fertiliser decisions tied to crop needs and soil advice. Write down each operation, quantity, area and cost.
Keep your local comparison useful
Use the same variety, sowing date, spacing and other management as far as practical in treated and comparison areas. Take counts and photographs at comparable points. Record soil variation and every difference in operations.
Necessary corrective work should protect the crop. Record the intervention and consider its effect when interpreting results. Early uniformity and roots can guide management, while marketable harvest and costs are still needed to judge the final return.
Prepare the next block before the seed arrives
Walk the unplanted block now. Review drainage, compacted traffic areas, surface cover and seedbed condition with your field adviser. Confirm seed, fertiliser, water, equipment, labour and input delivery before scheduling sowing.
If you plan HumiBakt soil application, follow the current pack directions. The current website soil-use guide lists 80 g in 80 litres of clean water per acre. Apply evenly to suitably moist soil and keep it out of the same tank as synthetic crop-protection chemicals. The mixing water is a carrier; plan the crop water supply separately.
Confirm the actual planting window for your sub-county and field. Check current Kenya Meteorological Department guidance and local soil conditions before work; this checklist does not predict the rainfall date.
Keep profit per acre in the record
Create a cost line for seed, preparation, fertiliser, soil inputs, application, labour and water. Keep receipts and assign costs to the measured block. At harvest, add harvesting, drying where applicable, transport and selling costs.
For each comparison area, measure marketable maize from a known area and record quality and the actual selling price. Revenue per acre minus recorded costs per acre gives the basis for a field-level decision. Larger early plants alone do not establish a financial return.
Use one review sheet for each block
Block and acres: ____ | Sowing date and variety: ____ | Observation dates: ____ | Plant counts at fixed points: ____
Gaps and soil conditions: ____ | Root observations: ____ | Operations and costs: ____ | Action, owner and next visit: ____
Send your maize planting date, county or sub-county, acreage and dated observations to your FSC or the HumiBakt Africa team. If the next block is still waiting, include its planned sowing date so we can discuss supply and soil application before planting. Let’s make it happen.
Questions from farmers
Does first 30 days mean the same visit dates for every farm?
No. Start from the actual sowing date and adjust visits to emergence, local conditions and agronomic advice. Blocks planted on different dates need separate records.
Should I replant every visible gap?
Ask your local maize adviser to assess plant population, gap pattern, crop age and field conditions before deciding. Record the cause and any corrective work.
Do stronger roots prove HumiBakt increased profit?
Root observations are useful early evidence. A profit assessment also needs a fair comparison, measured marketable harvest, selling price and full costs.
What if I have not sown maize yet?
Use this period to prepare the seedbed, confirm inputs and delivery, mark a comparison area and plan soil application. Make the sowing decision using local advice and actual field conditions.
What information should I send HumiBakt Africa?
Send your crop, county or sub-county, acreage, actual or expected sowing date, and dated observations. These details help plan supply and a useful field review.

Start the crop with living soil
Put HumiBakt’s humic substances and beneficial Bacillus bacteria into the root zone before planting. HumiBakt costs KES 3,500 per acre, including 16% VAT. Order online now or buy with guidance from your local FSC.
