A diferencia de algunas partes del país donde el otoño marca el final de la temporada de crecimiento, aquí en el desierto de Sonora, tenemos dos principales zonas de crecimiento. Estaciones, son una temporada de crecimiento fresco que dura aproximadamente desde octubre hasta mayo y una temporada de crecimiento cálido que dura desde mayo hasta mediados de septiembre. En cada una crecen diferentes hierbas. Temporada, y algunos, con un poco de ayuda, crecerán felizmente todos los años de duración.

Three randomized compete blocks with eight one square meter plots were tested at three locations; Tucson, Prescott, and Flagstaff, Arizona. Each of the mulches was subjected to the heat of a handheld propane torch (15 seconds), a glowing charcoal briquette (five minutes), and a lit cigarette (until burned out). We found that the least dense mulches (pine needles and straw) burned rapidly when subjected to the torch and ignited after the briquette was removed. The medium density mulches (pine bark nuggets and wood chips) had low flame lengths and smoldered. Heavy density mulches (garden compost and shredded bark) only smoldered. The decomposed granite and sod did not ignite or smolder.

When used thoughtfully, they contribute organic matter, supply essential plant nutrients, and support nutrient cycling. However, their use also requires careful management to avoid unintended impacts such as introducing weed seeds, spreading pathogens, or altering soil chemistry through salt or nutrient buildup. Understanding these risks and applying best management practices ensures that manure and compost remain beneficial tools for soil health and agricultural production. Arizona soils present unique challenges that make manure and composted manure especially relevant. In the state’s hot, arid climate, organic matter decomposes rapidly, leaving many Arizona soils with minimal organic matter for nutrient cycling (Bliss, 2003). These soils are often alkaline, with pH values ranging from 7.0 to 8.8, and may contain hardened layers of calcium carbonate (caliche). Although mineral-rich and geologically diverse, the high pH can limit plant uptake of micronutrients such as iron, manganese, and zinc. This combination of low organic matter and alkaline chemistry means that soil amendments, such as manure or composted manure, can provide significant benefits.

Kurapia (Lippia nodiflora; synonym Phyla nodiflora) is not a grass and not a clover. Kurapia is a broadleaf plant (eudicot) and a member of the Verbena family. Keen observers may notice Kurapia flowers resemble the flowers of Lantana, which is also a member of this plant family.
