“…Crop production depends greatly on soil fertility and the continuous decline in soil fertility is a major constraint to agriculture (Mucheru-Muna et al 2007). This decline in soil fertility is the result of natural and managerial activities such as leaching, erosion and crop harvest, continuous cultivation and overgrazing (Macharia et al 2011) and this decline of soil nutrients will continue unless there are means of replenishing the lost nutrients (Mucheru-Muna et al 2007).…”

“…Soil analysis at beginning and end of introduced forage legume experiment revealed that soil ph, carbon, nitrogen and potassium increased while calcium decreased significantly from the soil by end of the experiment. In this experiment the higher soil pH was probably due to addition of leaf litters and decay of roots and nodules by legumes (Macharia et al 2011). Decomposition and mineralization process released the nutrients from the organic residues and it enhanced due to increased microbial activities which accelerated by favourable soil condition and carbon availability (Landon 1984, Muriuki andQureshi 2001).…”

“…Forage legumes have potential to bind the soil aggregates with organic matter after decomposition of their residues hence these recognized as the soil building crops. Incorporation of legume residues in the soil enhanced the soil ph it might be due to decomposition and mineralization of organic residues by micro-organisms which resulted into increased soil ph (Macharia et al 2011). As a result of higher soil ph or less acidic condition nutrients such as carbon, nitrogen, phosphorus, potassium, calcium, magnesium, sulphur etc.…”

Forage legumes are contributing in sustainable crop production apart from nutritional security to the livestock. Forage legumes are crucial for the nutritional security for mankind as they are integral component for increased availability of animal protein and product which has higher biological value compared to plant proteins. The inclusion of forage legumes in crop production systems is more useful as these can not only provide food and feed to animals but also improves soil productivity and act as soil-conserving components of agricultural and agroforestry systems. Production system as a whole and tremendous deficit of forage nutritious resources demand in particular to give some importance to the forage crops especially leguminous forages. Therefore, critical assessment is necessary for determining the direction and magnitude of change in agricultural management practice with inclusions of forage legume. Forage legumes have good capacity as a feed to promote sufficient quantities and qualities required for different productive animals. Therefore, these crops can contribute to achieving the objectives of sustainable food/ fodder and environmental security. Hence, inclusion of legumes forages in cropping system is inevitable in advancing soil sustainability and food and nutritional security without compromising the long-term soil fertility base of the soil resources. Rational soil management practices must involve forage legume-based rotations and intercropping considerations for restoring soil health, and soil sustainability should be given due emphasis. Besides, forage legumes can also provide a wide range of benefits such as restoration of soil fertility, nitrogen fixation and fertilizer saving, enhancement of soil biology and biodiversity, improving soil carbon sequestration and by neutralizing negative impact of climate change. This review summarizes the potential role of forage legume in animal nutrition, soil fertility building, nitrogen fixation, soil biology and biodiversity, carbon sequestration, climate change and other ecological services provided.

“…Los contenidos oscilaron de 0.78 cmol kg -1 a 1.97 cmol kg -1 , lo cual es alto para todos los sistemas de uso de suelo. Estos resultados concuerdan con lo reportado por Aghasi et al (2011), quienes no encontraron variaciones en K y P en suelo de pastizales convertidos a agrícola, así como Macharia et al (2011) donde los valores de P no fueron signif icativamente diferentes. Por otra parte, los resultados de P y K fueron menores para la profundidad 5-30 cm a diferencia de la profundidad 0-5 cm, en este sentido, Rosolem y Calonego (2013) reportan en su estudio bajo diferentes sistemas de gestión de suelo y rotación de cultivos, una tendencia a la pérdida de P en el sistema suelo-planta y una lixiviación del K en la capa superf icial del suelo.…”

Las propiedades químicas son indicadoras de la calidad del suelo, las reservas nutritivas pueden modif icarse debido a las actividades antropogénicas. Para evaluar el efecto sobre las propiedades químicas de un suelo de tipo vertisol, se analizaron los nutrientes bajo cuatro sistemas de uso de suelo: matorral espinoso tamaulipeco, pastizal, cultivo agrícola y una plantación de eucaliptos, ubicados en el noreste del estado de Nuevo León, México. Se colectaron cuatro muestras de suelo compuestas por sitio a dos profundidades (0-5 cm y 5-30 cm) analizándose pH, conductividad eléctrica (CE), capacidad de intercambio catiónico (CIC), macronutrientes (K, Ca, Mg y Na) y micronutrientes (Cu, Mn, Fe y Zn). De acuerdo a los resultados obtenidos, se encontraron diferencias signif icativas (P ≤ 0.05) entre los sistemas de uso para pH, Mg (cmol(+) kg-1), Fe (mg L-1) y Cu (mg L‑1) en las dos profundidades. La CE (dS m-1), Zn (mg L-1) y CIC (cmol(+) kg-1), presentaron diferencias en la profundidad 0-5 cm, mientras que Ca (cmol(+) kg‑1), Na (cmol(+) kg-1) y Mn (mg L-1) para la profundidad 5-30 cm. Los nutrientes P (mg kg‑1) y K (cmol(+) kg‑1) no presentaron diferencias entre los sistemas en las dos profundidades. Se realizó una correlación de Spearman entre las variables, siendo el pH la variable que presentó una relación con la mayoría de los nutrientes, debido a la competencia entre cationes y el efecto de la disponibilidad de los micronutrientes. En los sistemas agrícola y plantación de eucalipto se presentó una disminución en K, Fe, Mn, Zn y CIC, mientras que en el pastizal los contenidos de P y K aumentaron a diferencia del matorral que representa la vegetación natural.
