Increasing Potato Production

21.06.2010
Using soil structure and chemistry to define yield influences

Despite sophisticated nutrient management of potato crops, quality and yield still see wide variability. Although nutrients are already well understood, the influence of other environmental factors remains understudied.

A research team from Michigan State University conducted a study to determine how the chemical and physical properties of soil, along with the light waves the plant absorbs and reflects, affect potato yield and variability. These findings were integrated with known factors to provide a more complete understand of the influences on potato growth.

Sieglinde Snapp and Alexandra Kravchenko from Michigan State University, and Edgar Po from the University of Missouri reported their findings in the May-June 2010 Agronomy Journal, published by the American Society of Agronomy. Measured across many different soil chemical and physical properties, they found that soil structure was a significant variable that contributed to positive potato yield across coarse-textured commercial field sites.

The study demonstrated the need to supplement monitoring of soil chemical properties, which is a common practice, with data on soil structure and spectral profiles. Soil structure improvement requires dedicated management, but stable soil particle size and their stability in water was a sensitive predictor of field-level variability in potato tuber yield.

This research indicates the potential for considerable long-term benefits from understanding and improving soil biophysical characteristics. Supplementing traditional soil sampling with spectral measurement provided a detailed image of how the potato crop interacted with its environment. This method allowed researchers to notice differences in growth and development of the potato crop due to changes in planting dates, as well as precipitation patterns.

The study was conducted on potato, but the authors noted that the methodology appears to be widely applicable. By expanding being meeting the immediate nutritional requirements of the crop, farmers and other agricultural producers should be able to achieve higher yields.

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
