FORTRESS wheat and maize (corn) production:

Weather patterns, international and national agricultural market movements, as well as new technical developments in agriculture are repeatedly challenging them to be flexible and adjust their crop planning where feasible.

Following international trends FORTRESS constantly improves productivity by “no till” or at least “minimum tillage”. In 2007 they started to double crop in one growing season, maize after wheat under irrigation.  Challenges such as plant residue chopping and seedbed preparation had to be solved.

Double cropping of wheat and maize under irrigation, required FORTRESS to use wheat straw and maize residues to their maximum advantage, utilising the resultant mulch to improve soils.  This is achieved by a combine harvester (Claas) fitted with a chopper and spreader for wheat straw.  In case of maize the combine harvester is fitted with a picker and chopper head (Geringhoff).

The use of artificial fertilisers was drastically reduced by using their own compost.  For more information on compost making, click on “Other FORTRESS activities” on this website.

FORTRESS reduced their water consumption for irrigation by about 25 % after installing moisture sensors in the soil under irrigation.  The sensors automatically feed moisture data to the management computer.

No Till / Minimum Tillage

In 2007 the No Till / Minimum Tillage project was started as is customary, step by step! During his visit to FORTRESS Gary Zimmer (USA) said: “You cannot just start no till, you have to earn it”. Crop residues are now left to naturally break down and thus improving soil structure by applying compost and adequate lime as per the ALBRECHT system.
