Texas Tech, Nanjing Agricultural Research Teams Make Plant Nutrient Delivery Breakthrough - Seed World

Submitted by Elsewhere on 2020-Sep-18 Fri 12:14

When most people think of fungi, the thoughts are usually not good, turning to something that does damage more than those that are actually helpful.

Yet, fungi play a critical role in the growth and development of plant life and have for millions of years. Scientists have known for a long time that arbuscular mycorrhizal (AM) fungi that live in harmony with about 90% of land plants and play a key role in their root systems, are responsible for carrying needed phosphate to plants to help growth.

Now, however, thanks to a discovery by a team of scientists from Texas Tech University’s Institute of Genomics for Crop Abiotic Stress Tolerance (IGCAST) in the Department of Plaint and Soil Science, and the Nanjing Agricultural University’s State Key Laboratory of crop Genetics and Germplasm Enhancement, that symbiotic role may go even further.

That research team, which included professor Guohua Xu, Prof. Aiqun Chen and Dr. Huimin Feng from Nanjing Agricultural University and, Luis Herrera-Estrella, the President’s Distinguished Professor of Plant Genomics and director of IGCAST, and assistant professor Damar López-Arredondo, discovered that AM fungi also acted as a supplier of nitrogen to the plant, the protein (NPF4.5) responsible for transporting nitrates from the fungi to the plant, and that this symbiotic nitrate pathway and the function of the protein are present in crops such as rice, and probably most other plant species.

Nutrient solution analysis projects for greenhouses and vertical farms

Submitted by Elsewhere on 2020-Sep-10 Thu 10:25

The quality of water and nutrient solution used in controlled environment agriculture (CEA) production systems, such as greenhouses and vertical farms, is one of the most important factors that affect plant health and yield. Growers monitor water and nutrient solution quality by sending samples for…

Greenhouse, outdoor, or indoor: Which kale is healthiest?

Submitted by Elsewhere on 2020-Sep-08 Tue 10:12

Urban populations have plenty of access to calorie-dense, nutrient-poor foods. In order to move to a healthier diet, however, they need access to vegetables and other micronutrient-dense foods, according to Danish economist Per Pinstrup-Andersen, who says it's time to take vertical indoor farming…

The development of an online indicator related to plant nutritional aspects

Submitted by Elsewhere on 2020-Sep-03 Thu 09:28

Electrical conductivity of the growing media or drainage indicates the nutritional conditions in the cultivation system. However, the nutrient uptake phenomenon has not been related well to the soilless culture system. In a recent study, there is reported on the design, theoretical analyses, and…

Overview of mineralisation in an aquaponic system

Submitted by Elsewhere on 2020-Aug-26 Wed 11:04

Aerobic mineralization is very similar to Aerated Compost Tea (ACT) or Actively Aerated Compost Tea (AACT) and is one of the easiest ways to grow more plants using less fish in aquaponic or aquaculture systems.  You may already have heard of ACT or ACCT being used in the soil systems thanks to the hard work…
