Crop systems and fertilization sources can affect the chemical properties of the soil and, consequently, its fertility. With the aim of evaluating the effect of such management practices, soil samples collected at 0.0-0.10; 0.10-0.20; and 0.20-0.40 m in depth were collected and analyzed in the second year of an experiment installed in 2006 in a Rhodic Hapludox under no-till farming, located in ...

Aim of study: To evaluate agronomic performance and changes on soil chemical properties in two types managements: conventional or sustainable.Area Principality Asturias, Spain.Material methods: On a sandy-clay-loam texture soil, three winter forage legumes (faba bean, red clover white lupin), monoculture mixed with Italian ryegrass organic fertilization (sustainable management) versus inorganic...

in this study, the effect of hormon ovafact (gnrha) on biological semen characteristics (motility duration, percentage of motile spermatozoa, spermatocrit, sperm density, milt volume, ph, na+, k+, ca+, mg2+, total protein, cholesterol and glucose) in sub species commons, comets, wakins and fantail goldfish (carassius auratus gibelio) males was compared. from each treatment ten males has been in...

Background: This study was carried out to assess the effects of MnTBAP, a cell permeable antioxidant, on motility, membrane integrity, capacitation status and in vitro fertilization ability of frozen-thawed ram semen. Materials and Methods: Fresh semen ejaculates were collected with artificial vagina from five rams, mixed and divided into five equal fractions, and diluted (1:20 v/v) with commer...

Current climate and human-induced changes are projected to alter many regimes of ecosystem functioning. It is projected that invasive species, nonnative species that can be of great detriment to an ecosystem, will benefit under these conditions. The Prairie Invasion and Climate Experiment (PRICLE) studies the effects of two global change factors – N addition and altered precipitation – on invas...

The Kryptolebias marmoratus is unique because it is the only self-fertilizing hermaphroditic vertebrate, known to date. It primarily reproduces by internal self-fertilization in a mixed ovary/testis gonad. Here, we report on a high-quality genome assembly for the K. marmoratus South Korea (SK) strain highlighting the diversity and distribution of transposable elements (TEs). We find that K. mar...

Maintaining soil fertility and the microbial communities that determine fertility is critical to sustainable agricultural strategies, and the use of different organic fertilizer (OF) regimes represents an important practice in attempts to preserve soil quality. However, little is known about the dynamic response of bacterial communities to fertilization regimes across crop growth stages. In thi...
