How insect predators can help you

Beneficial insects used in integrated pest management (IPM) can sometimes completely eliminate the need for crop chemicals, or at least reduce chemical spraying to a minimum.

Benefits of a germination room

One of the crucial factors in seedling production is achieving a high and uniform germination. A loss in germination of just a few percent translates into a similar reduction in profit.

Tips on planting cucurbits

Some farmers, especially at the end of winter, use seedlings for their cucurbit crops in an attempt to get an early-growth advantage and better prices.

Garlic (Allium sativum) can be grown in a wide range of soil types. What is more important is good fertility, as this crop has a modest root system.
