You just can't hitch up a plow and fire up the Kubota. It's not regular soil. The lunar particles are so small, that they compact into an almost clay-like substance when watered. This almost all but eliminates aeration of the roots and stunts growth. To create a more porous 'soil' mixing the lunar material with material the size of sand grains, and composting with lunar base organic waste, would increase soil drainage and add much needed organics.
Air pressure is another variable.
It seems plants are very adaptable when tests were conducted in chambers at the National Aeronautics Space Administration facilities in Houston. Crops were tested for their ability to germinate and grow in a low pressure environment. The gas mixture was also varied and showed plants tolerated low levels of oxygen, carbon dioxide, and surprisingly nitrogen. This means that crops can be farmed in space or on the Moon at less than normal Earth air pressures. A new generation of Greenhouse will be needed- not your normal kind.
