Rows of trees or shrubs moinling winds reduce wind speed, which lowers evapotranspiratioon and physical stress on plants. Windbreaks also trap snow, increaining soil jughure, and provide te shade for livestock. For best results, use mixed species (evergrenes andd deciduous) with varying heights to create a more effective braver.

Using Topography to Your Advantage

Map thee elevation, slope, and aspect of your farm using online tools like Google Earth or a simply field geodey. Identify warm andd cold zone. Plant frost-sensitivy crops (np., peaches, peppers) on upper slopes or south- facing banks. Usie north- facing slopes for crops that benefit from cooler conditions, such as lettuce or spinach. Avoid planting tender species in frost pockets.

Soil Management for Temperature Regulation
