Comparisons of the Forage Productivity and Mineral Contents Between the Newly Reclaimed and Arable Pasture Soils II. Changes in the soil properties, vigour at early growth, yields, and mineral nutrients of forages as affected by lime application

An experiment was conducted in the laboratory of the Department of Agricultural Chemistry, Bangladesh Agricultural University (BAU), Mymensingh to determine protein and major mineral nutrients (viz. Ca, Mg, Na, K, P, S and Fe) in different available fish species of the Brahmaputra River of Bangladesh. Total 32 fish samples of 15 fish species were collected from three locations of the river during November 2017. The highest amount of Ca (2.00%), Mg (4.17%), Na (0.41%), K (3.24%), P (0.17%), S (0.129%) and Fe (226.9 mg kg−1) were obtained from chela (Salmophasia bacaila), chanda (Chanda nama), chingri (Macrobrachium sp.), shingi (Heteropneustes fossilis), bele (Glossogobius giuris), baim (Macrognathus aculeatus) and mola (Amblypharyngodon mola), respectively and the sequence of the mineral nutrients was K > Mg > Ca > Na > P > S > Fe. The study results revealed that 100% of daily Ca requirement can be replenished by consuming 100 g fish flesh portion of the chela (Salmophasia bacaila)/ chingri (Macrobrachium sp.)/ bele (Glossogobius giuris). Similarly, among the 15 fish species, 11 and 12 species alone can contribute 100% of Mg and K requirement for human by taking 100 g fish flesh, respectively. The maximum content of N (3.88%) was obtained from shingi (Heteropneustes fossilis), while the minimum (2.81%) was recorded from mola (Amblypharyngodon mola). The protein content among the fish samples varied between 17.6-24.3% with a mean value of 21.2%. Finally, the study results concluded that the common fishes available in the Brahmaputra River are a good source of protein and major mineral nutrients, which contributes in nutrition to the local people of the country.

Con el propósito de que plantas de frambuesa cultivadas en sustrato de peat moss y perlita, adquirieran una mayor cantidad de nutrientes minerales de los que comúnmente obtienen de una solución nutritiva completa en cultivo sin suelo, aquí se reporta el efecto de enriquecer el medio de crecimiento (sustrato) con diferentes moliendas de rocas minerales ricas en nutrientes (roca fosfórica, riolita, diatomita, dolomita, zeolita y harina de basalto) de las cuales se aplicaron 15 g por tratamiento a cada planta de frambuesa (Rubus ideaus L.) variedad fx1522. Con las aplicaciones de las diferentes rocas molidas se incrementó en frutos el contenido mineral de K, P, Ca, Mg, S, y Cu en 27, 27, 42, 33 y 44 %, respectivamente. Con respecto a la actividad enzimática de la catalasa se encontró que con riolita, diatomita y zeolita aumentaron en 54, 45 y 34 % respectivamente comparados con el testigo. La actividad de superóxido dismutasa y el contenido de vitamina C no se vieron afectadas por los tratamientos. El tratamiento con zeolita incrementó los compuestos fenólicos en un 23 %.ABSTRACTIn order for raspberry plants cultivated in an inert growing medium of peat moss and perlite acquire a greater amount of mineral nutrients than they commonly obtain from a complete nutrient solution in soilless culture, here we report the effect of amending the soilless growing medium with different ground mineral rocks (mills) rich in nutrients (phosphate rock, rhyolite, diatomite, dolomite, zeolite and basalt flour) of which 15 g were applied per treatment to each raspberry plant (Rubus ideaus L.) variety fx1522. The applications of different ground rocks increased the fruits K, P, Ca, Mg, S, and Cu mineral contents by 27, 27, 42, 33 and 44 %, respectively. Regarding the CAT enzymatic activity, it was found that the treatments with riolite, diatomite and zeolite increased 54, 45 and 34 % respectively when compared against the control plants. Superoxide dismutase activity and vitamin C content were not altered by the treatments. The treatment with zeolite increased the phenolic compounds by 23%.
