Limnological variables and nutritional content of submerged aquatic macrophytes in a tropical lagoon

Analyses of the tissue content of phosphorus (P), calcium (Ca), potassium (K) and sodium (Na), and carbon and nitrogen stable isotopes, were used to assess nutritional status

The increase in nitrogen doses promoted significant increments in dry matter productivity, number of tillers, total nitrogen content, crude protein and relative chlorophyll

Suspended sediment concentration, total phosphorus content (Total-P), total organic carbon (TOC), and proportion of organic (Organic-P) and inorganic (Inorganic-P) P in relation to

Nitrogen and phosphorus content in plant and phosphorus in the soil, total number of ears (TNE), total weight of ears (TWE), total number (TNMUE) and weight (TWMUE) of

A partir das considerações expostas, este trabalho busca conhecer a importância da Embrapa Semiárido para o desenvolvimento socioeconômico do polo Petrolina-PE

Levels of total soil organic carbon, as well as oxidizable fractions and aggregate stability, were analyzed, in addition to the activity and carbon and nitrogen content in the

High nitrogen compounds and total phosphorus in the culture media are due to concentrations of nutrients in the inorganic fertilizer and aquatic plants.. The composition of
