Rather than being homogeneous, it's a layered affair of water, nutrients and organisms.
Aerating the soil helps water, nutrients and oxygen move into the soil, rather than running off.
Elimination of weeds is important, because they compete for water, nutrients, and light.
Competition between trees is actually more severe under limiting conditions (water, nutrients, or light) than it is under toxic conditions.
Soils are dynamic, open habitats that provide plants with physical support, water, nutrients, and air for growth.
Below the ocean's surface, the deeper pool of warm water has reduced the usual upwelling of deep water nutrients to the surface of the Eastern Pacific.
"Essentially, the microbes that cause rotting are a lot like ourselves, in that they need water, nutrients, warmth and time to grow.
Trees must compete every second for "water, nutrients, light and space; and to fend off cold, heat, drought, flood, toxicity and the host of parasites and predators of all conceivable kinds," he writes.
As the lake swells, the raw materials for fish production flow in: water, nutrients, adult female fish ready to spawn, and larval or juvenile fish that were spawned upstream and have been riding the rising tide downstream.
A high-definition spectrophotometer was used for estimating the concentration of major water nutrients.
A highly equipped spectrophotometer was used for estimating the concentration of water nutrients.
