N-fixing black locust intercropping improves ecosystem nutrition at the vulnerable semi-arid Loess Plateau region, China.

The Loess Plateau in northwestern China constitutes one of the most vulnerable semi-arid regions in the world due to long-term decline in forest cover, soil nutrient depletion by agricultural use, and attendant soil erosion. Here, we characterize the significance of N-fixing Robinia pseudoacacia L. and non-N-fixing Juglans regia L.

ATP as Phosphorus and Nitrogen Source for Nutrient Uptake by and x Roots.

The present study elucidated whether roots of temperate forest trees can take up organic phosphorus in the form of ATP. Detached non-mycorrhizal roots of beech () and gray poplar ( x ) were exposed under controlled conditions to P-ATP and/or C/N labeled ATP in the presence and absence of the acid phosphatase inhibitor MoO . Accumulation of the respective label in the roots was used to calculate P, C and N uptake rates in ATP equivalents for comparison reason.

Metabolome and Lipidome Profiles of × Twig Tissues During Annual Growth Show Phospholipid-Linked Storage and Mobilization of C, N, and S.

The temperate climax tree species and the floodplain tree species × possess contrasting phosphorus (P) nutrition strategies. While has been documented to display P storage and mobilization (Netzer et al., 2017), this was not observed for × (Netzer et al.

Seasonal Alterations in Organic Phosphorus Metabolism Drive the Phosphorus Economy of Annual Growth in Trees on P-Impoverished Soil.

Phosphorus (P) is one of the most important macronutrients limiting plant growth and development, particularly in forest ecosystems such as temperate beech () forests in Central Europe. Efficient tree internal P cycling during annual growth is an important strategy of beech trees to adapt to low soil-P. Organic P (P) is thought to play a decisive role in P cycling, but the significance of individual compounds and processes has not been elucidated.

Phosphorus nutrition of Populus × canescens reflects adaptation to high P-availability in the soil.

Phosphorus (P) constitutes one of five macronutrients essential for plant growth and development due to the central function of phosphate in energy metabolism, inheritance and metabolic control. In many ecosystems, plant available soil-P gets limited by soil aging. Hence, plants have developed adaptation strategies to cope with such limitation by an efficient plant and ecosystem internal P-cycling during annual growth.
