Wet winter concerns: Phytophthora and waterlogging

Excessive water, caused by rain, flooding, or even overirrigation, is a challenge for orchards and can cause two very different problems: waterlogging and Phytophthora infection. Given that we had bountiful rain this winter and orchards with standing water were common, continuous monitoring and collaboration with your PCA or farm advisor will be increasingly valuable.

Vegetation for Infiltration

Facing a fourth consecutive year of drought conditions across California, and pressures to preserve existing water reserves has led to more California growers taking interest in incorporating some form of agriculturally managed recharge (AG-MAR) into their water management plans. Read further to learn how cover crops can help divert runoff from winter storms into groundwater basins for future use. Continue reading

When do you shake almonds?

Historically, the recommendation from UC almond experts for the ideal time to shake was as soon as 100% hull split occurred throughout the orchard, however, these considerations vary widely among varieties and locations. Potential challenges that growers should consider when timing harvest include pest and disease management, nut removal/drying time, and nut quality. Continue reading

Is it time for a closer look at alternative nutrient sources?

With continued tight nut markets and high input costs, it’s worth considering all nutrient input options in an effort to lower costs and maintain production. Sustainable nutrient management includes assessment of irrigation nitrate, adding compost manure amendments or almond shells, and using nitrogen-fixing cover crops. Continue reading

Pistachio Nitrogen Nutrition: What do we know and how do we manage?

Given that N fertilizer mismanagement have increased significantly and the Irrigated Lands Regulatory Program (ILRP) have implemented new regulations to prevent agricultural runoff from impairing surface waters, it only makes sense to use available tools to improve Nitrogen Use Efficiency (NUE). This article provides more information about what tools are available. Continue reading
