During this hot summer, every grower was wondering how his potato crop would deal with the drought. In order to keep the crop growing, there is no doubt this season that irrigation is necessary. Which plot is the most urgent and how long can a grower wait until the next bout of irrigation is needed without losing too much production? According to Professor Wim Bastiaansen of Aurea Imaging BV and TU Delft, there is a practical need for a simple soil moisture monitor. In this article, the scientist describes a number of methods with their advantages and disadvantages. His main conclusion is that none of the methods is accurate enough in itself to determine the exact moment of irrigation, but that a combination offers more possibilities.

Agritechnica focus on trends in potato technology
From 12-18 November Agritechnica takes place in Hannover, Germany. During the event there is a main focus on potatoes. Dr. Rolf Peters presents his vision on trends in potato technology. He states that potato growing has required a particularly high degree of flexibility from farmers in this year’s growing season due to the intensive change…
The efficiency of overhead irrigation for potato crops
Irrigation with sprinklers, rain guns, center pivots or linear systems – as opposed to furrow and drip irrigation delivering water under the canopy – distributes water overhead, much like natural rainfall does.
The advantages of drip irrigation in potato cultivation
Of all irrigation practices, furrow irrigation loses most water through drainage and also loses more nitrogen through leaching than other irrigation practices. Drainage through deep percolation on the other hand is an advantage as it avoids accumulation of salts at the surface. Besides, erosion is considerable as the water flow to some extent always transports…
Furrow irrigation in potato cultivation
Where there is not enough rainfall and evapotranspiration exceeds precipitation, the crop is irrigated. That is if there is surface water or underground water available at acceptable distance and depth from the field. What is more, the grower needs to have available the capital to invest in equipment. The irrigation technique requiring the least investment…
