Comparison of Water Capture Efficiency through Two Irrigation Techniques of Three Common Greenhouse Soilless Substrate Components

Submitted by Elsewhere on 2020-Sep-14 Mon 10:26

Substrate wettability is an important factor in determining effective and efficient irrigation techniques for container-grown crops. Reduced substrate wettability can lead to lower substrate water capture, excessive leaching and poor plant growth. This research examined substrate water capture using surface and subirrigation under three initial moisture contents (IMC). Sphagnum peat moss, coconut coir, and pine bark were tested at IMCs of 67% 50%, and 33%. Substrate water capture was influenced by both IMC and irrigation technique. Surface irrigation increased the water capture of coir and peat, regardless of IMC, whereas IMC influenced pine bark water capture more than irrigation method. Surface-irrigated coir at or above 50% IMC provided the greatest water capture across all treatments. The first irrigation had the highest capture rate compared to all other events combined. Container capacities of pine bark and coir were unaffected by IMC and irrigation type, but the CC of peat was less by ~ 40% volumetrically under low IMC conditions. Coir, had the greatest ability to capture water, followed by pine bark and peat, respectively. Moisture content, irrigation type and component selection all influence the water capture efficiency of a container substrate.

Increasing Sustainability of Growing Media Constituents and Stand-Alone Substrates in Soilless Culture Systems

Submitted by Elsewhere on 2020-Sep-14 Mon 10:26

Peat-free growing media constituents and stand-alone substrates are the basis for the economic and ecological efficiency of the soilless culture system. Nevertheless, divergence between the model and practice still exists, coming from large gaps in the knowledge of alternative organic materials and of their effects on crop performance. A more detailed understanding of these topics is necessary to increase the soilless culture management capacity. In this respect, this critical review collects research outcomes concerning the sustainability of soilless culture and growing media constituents and their impact on the environment. In particular, the review covers designated articles stressing the pros and cons of soilless culture and growing media constituents, the exploitation of different organic materials and their economic and environmental relevance.

What is aeroponics, and how could it make agriculture more sustainable?

Submitted by Elsewhere on 2020-Sep-10 Thu 10:23

A crop that uses an aeroponic method relies on mist and air to grow rather than soil. It’s an inventive way to avoid aggregates that traditional agriculture methods require. Each plant receives nutrient-rich moisture through a spritz to its roots. This practice allows growers to create a flexible, mobile garden wherever they please.

Substrate handling influences water holding capacity

Submitted by Elsewhere on 2020-Sep-08 Tue 10:13

Water holding capacity is greatly influenced by the size of the growing medium particles. Coarse particles create macropores which account for drainage and air porosity, while fine particles create micropores which retain water. A mixture of coarse and fine particles can be prejudicial for a substrate…

Partial root-zone drying and deficit irrigation effect on greenhouse grown grafted tomato

Submitted by Elsewhere on 2020-Sep-04 Fri 08:22

The tomato is an important horticultural crop, the cultivation of which is often under influence of abiotic and biotic stressors. Grafting is a technique used to alleviate these problems. Shortage of water has stimulated the introduction of new irrigation methods: deficit irrigation (DI) and partial…

Special Starting Material

Submitted by Elsewhere on 2020-Sep-01 Tue 09:16

Good quality starting material is very important in the horti- and floriculture sector. The quality of the crop is inextricably linked to the quality of the starting material that has been used. With virus pressure getting higher and higher, this subject has become even more important. Therefore, this month we are focusing on…
