Cropland rental market and farm technical efficiency in rural Vietnam authored by Hoang Trieu Huy, Trung Thanh Nguyen Abstract Increasing farm technical efficiency in developing countries is essential to raise farm productivity, and cropland rental market is theoretically expected to contribute to farm production efficiency growth.

Acidification of European croplands by nitrogen fertilization Consequences for carbonate losses, and soil health verfasst von Kazem Zamanian, Ruhollah Taghizadeh Mehrjardi, Jingjing Tao, Lichao Fan, Sajjad Raza, Georg Guggenberger, Yakov Kuzyakov Abstract Soil acidification is an ongoing problem in intensively cultivated croplands due to inefficient nitrogen N fertilization.

Earth observation data driven cropland soil monitoring A review verfasst von Nikolaos Tziolas, Nikolaos Tsakiridis, Sabine Chabrillat, Jos A.M. Demattê, Eyal Ben Dor, Asa Gholizadeh, George Zalidis, Bas van Wesemael Abstract We conducted a systematic review and inventory of recent research achievements related to spaceborne and aerial Earth Observation EO data driven monitoring in support of soil related strategic goals for a three ye...

Croplands conversion to cash crops in dry regions Consequences of nitrogen losses and decreasing nitrogen use efficiency for the food chain system verfasst von Xuechen Zhang, Bahar S.

Acidification of European croplands by nitrogen fertilization Consequences for carbonate losses, and soil health authored by Kazem Zamanian, Ruhollah Taghizadeh Mehrjardi, Jingjing Tao, Lichao Fan, Sajjad Raza, Georg Guggenberger, Yakov Kuzyakov Abstract Soil acidification is an ongoing problem in intensively cultivated croplands due to inefficient nitrogen N fertilization.

An example of how this can be achieved in the context of quality assessment of cropland and grassland GIS objects is given in this paper. The quality assessment of these objects of a topographic dataset is carried out based on multi temporal information.

Vulnerability and driving factors of soil inorganic carbon stocks in Chinese croplands verfasst von Jingjing Tao, Sajjad Raza, Mengzhen Zhao, Jiaojiao Cui, Peizhou Wang, Yueyu Sui, Kazem Zamanian, Yakov Kuzyakov, Minggang Xu, Zhujun Chen, Jianbin Zhou Abstract The long term stability of soil inorganic carbon SIC and its minimum contribution towards global C cycle has been challenged, as recent studies have showed rapid decreases in SI...

Automatic qualtiy control of cropland and grasland GIS objects using ikonos satellite imagery verfasst von P. Helmholz, C. Heipke, F. Rottensteiner Abstract As a consequence of the wide spread application of digital geo data in Geoinformation Systems GIS , quality control has become increasingly important.

Here, we examined the effects of soil fertility quality on microbial community structure that identified by pyrosequencing and functions that predicted by the FAPROTAX functional annotations dataset after forest conversion to vegetable cropland and tea plantations. Soil quality index was significantly increased after natural forest 0.2 conversion to vegetable cropland 0.7 and tea plantations 0.3 0.6 . Soil bacterial beta dive...

Meta analysis on the effects of types and levels of N, P, and K fertilization on organic carbon in cropland soils verfasst von Yuhuai Liu, Chuan Li, Guan Cai, Leopold Sauheitl, Mouliang Xiao, Olga Shibistova, Tida Ge, Georg Guggenberger Abstract Most agroecosystems receive inputs of anthropogenically derived nutrients, which impact soil organic carbon SOC .
