Are your potatoes getting enough calcium?

Calcium is a vital nutrient for potatoes and most aspects of tuber quality can be improved by having a sufficient supply of calcium during growth. It is required in the crop for the maintenance of cell walls, healthy leaf and tuber development. Calcium prevents a wide range of tuber quality problems. Calcium deficiency is widely known as internal rust spot – a[Read[Read More…]

Late blight scare: Migrant European pathogen generated aggressive new variants in India, not yet found elsewhere globally

An international team of scientists from several countries including India, the UK and the US examined the population structure of the Phytophthora infestans pathogen that caused the 2013–14 late blight epidemic in eastern and northeastern India. Their findings were published online recently in the journal Nature.The data provide new baseline information for populations of P. infestans in India. It was found that a migrant European[Read[Read More…]

Nutrients 101: Nitrogen and potassium interactions explained

In this month’s newsletter published by the Potash Development Association (PDA), it is said that Justus von Liebig’s Law of the Minimum states that yield is proportional to the amount of the most limiting nutrient, whichever nutrient it may be. Nitrogen is the nutrient that most frequently provides the largest response, suggesting that this is usually most limiting. However, the plant-available potassium status[Read[Read More…]

Calcium prevents a wide range of tuber quality problems

Calcium deficiency is widely known as internal rust spot – a physiological internal defect in which small brown spots, due to cell death, appear in the tuber. This is directly related to a lack of calcium within the cell walls, meaning that they aren’t strong enough and when cell expansion takes place they collapse and necrosis occurs. Once calcium is incorporated[Read[Read More…]

Yara’s N-Sensor: A tool that twins science with sense

There are two aspects, you could argue, that define the real cutting-edge technological advances in today’s agricultural equipment – tools that generate vast arrays of utilisable data, and kit that has the capability to use this information and make decisions in real time that are even better than those made by a skilled operator or agronomist. But there’s one tool that’s[Read[Read More…]

Sensor brings new wavelengths to crop scanning for needs-based nitrogen

It only makes sense to apply fertilizer where it’s needed, and only where it’s needed. For a long time, agricultural machinery and technology companies have focused on achieving this goal, including German company Fritzmeier Umwelttechnik. The company’s technology, called the ISARIA Crop Sensor, uses four different wavelengths delivered with LEDs and up to 2000 measurement values per second to index vegetation. Mounted on the front[Read[Read More…]
