Smart Farming Kenya

Market & Field

Commodity prices, fertiliser and pest pressure in Kenya, from market data and sensor readings rather than press releases.

Fertiliser subsidy: which bags you can get and what they cost

The subsidy is a discount on six named products, capped per farmer and moving through depots on a schedule that has slipped before. In 2022 DAP fell from Ksh 6,500 to Ksh 3,500 a bag, but only for those who reached stock in time.

Farm gate, market or aggregator: which one pays you more

The quoted price per kilo is the least useful number in the decision. In Narok, wheat fell from 15 bags an acre to three, yet the gate price rose only about 30 percent, from Sh2,700 to Sh3,500 a bag.

Your own soil and leaf readings show pest risk building before any forecast does

A survey of 4,272 Kenyan farmers who received 8.8 million SMS forecasts found the messages mostly helped with planting date. But a tomato wilt disease turns destructive as soil nears 27C, and only a probe in your ground shows that.

Count your pests first, then decide whether a spray is worth it

Maryland's guide sprays cabbage once 20 percent of plants carry caterpillars; no such table exists for Kenyan kale. What transfers is the structure - a named pest, a countable unit, a number, a crop stage - and a notebook you start this season.

Soil fertility

How long manure keeps feeding your soil after you stop applying it

A report on compost made by bugs says orders are outrunning supply, but no multi-year trial backs it. The Embu goat manure trial does have the numbers, including a nine-year decline under mineral-only feeding.

Is the cheaper fertiliser in the next county worth the trip?

Global prices moved a 50 kg bag from 20 dollars to 48 in a year, so the local gap is only part of the story. What the ground under your crop can do with the bag decides the rest.

Short rains input planning: go by soil moisture, not the first shower

Rain totals across eight of our stations ran from 0.0 to 157.6 mm in the same three weeks, and probe readings from 18 to 92 percent of scale. Buying inputs early fixes availability, not timing.

Which maize seed to buy this season in Kenya

Kenya is importing 25 million bags of maize to cover a shortfall. That number says nothing about which variety sits in the sack at your local agro-dealer. This piece follows that decision from the national number down to a single block, with the figure that governs each link.

Fertiliser timing: why the calendar date is the wrong reason to top-dress

Extension sheets tell farmers to top-dress six weeks after planting. The trial data says the soil under the crop matters more than the date on the sheet.

How much water maize needs at each growth stage

Every irrigation pamphlet has a table of maize water needs in millimetres per stage. The method behind those numbers does not produce a fixed table, it produces a moving target that depends on your county, your planting date, and the week's weather.

Why fertiliser prices differ so much between Kenyan counties

A bag of DAP can cost Sh2,500 at one depot and the full market rate at the next vendor, and the difference is rarely about which county either sits in. This piece works through the channels, what each one actually costs, and where a farm's own monitoring data changes the calculation.
